Pull request description:

  A few follow-ups to #33689, includes:

  1) `ThreadPool` active-wait during shutdown:
  Instead of just waiting for workers to finish processing tasks, `Stop()` now helps them actively.
  This speeds up the JSON-RPC and REST server shutdown, resulting in a faster node shutdown when many requests remain unhandled. This wasn't included in the original PR due to the behavior change this introduces.

  2) Decouple `HasReason` from the unit test framework machinery
  This avoids providing the entire unit test framework dependency to low-level tests that only require access to the `HasReason` utility class. Examples are: `reverselock_tests.cpp`, `sync_tests.cpp`, `util_check_tests.cpp`, `util_string_tests.cpp`, `script_parse_tests.cpp` and `threadpool_tests.cpp`. These tests no longer gain access to unnecessary components like the chainstate, node context, caches, etc. It includes l0rinc's `threadpool_tests.cpp` `HasReason` changes.

  3) Include response body in non-JSON HTTP error messages
  Straight from pinheadmz [comment](https://github.com/bitcoin/bitcoin/pull/33689#discussion_r2783817192), it makes debugging CI issues easier.

dbbb780af0 test: move and simplify BOOST_CHECK ostream helpers
Move the operator<< overloads used by BOOST_CHECK_* out of the
unit test machinery test/setup_common, into test/util/common.h.

And replace the individual per-type ToString() overloads with
a single concept-constrained template that covers any type
exposing a ToString() method. This is important to not add
uint256.h and transaction_identifier.h dependencies to the
shared test/util/common.h file.

f3887cf694 Merge bitcoin/bitcoin#34561: wallet: rpc: manpage: fix example missing fee_rate argument
50cf6838e6 wallet: rpc: manpage: fix example missing `fee_rate` argument (SomberNight)

Pull request description:

  The function signature for the `send` RPC is:
  ```
  send [{"address":amount,...},{"data":"hex"},...] ( conf_target "estimate_mode" fee_rate options version )

  The last example in the manpage is missing the `fee_rate` arg, but is trying to specify the `options` arg, by index. The parser confuses the intended `options` arg as the missing `fee_rate` arg.

Pull request description:

  The miniscript parser currently only looks for the next `)` when parsing key, hash, and locktime expressions. This fails to parse when the expressions contain a nested expression. Currently, this is only possible with `musig()` inside of key expressions. However, this pattern can be generalized to handling hashes and locktimes, so I implemented those too.

  Fixes #34076

c1355493e2 refactor: fees: split fee rate format from fee estimate mode
- Introduce a `FeeRateFormat` enum and change `CFeeRate::ToString()`
   to use it for `BTC/kvB` vs `sat/vB` output formatting.
 - Handle all enum values, hence remove default case in `CFeeRate::ToString()`
   and `assert(False)` when a `FeeRateFormat` value is not handled.
 - Keep `FeeEstimateMode` focused on fee estimation behavior by removing fee rate format
   values from `FeeEstimateMode`.
 - Update all formatting call sites and tests to pass `FeeRateFormat` explicitly, separating fee rate format
   from fee-estimation mode selection.

Pull request description:

  Bundle all function's outputs inside the `util::Result` returned object.

  Removals:
  - The input-output 'change_pos' ref arg from `createTransaction`, which has been a source of bugs in the past.
  - The 'fee' ref arg from `createTransaction`, which is currently only set when the transaction creation process succeeds.
  - The no longer needed `AmountWithFeeExceedsBalance` error (more info about its re-introduction at [bitcoin#25269](https://github.com/bitcoin/bitcoin/pull/25269) and [bitcoin#34299](https://github.com/bitcoin/bitcoin/pull/34299).

  Additionally, this PR moves the `CreatedTransactionResult` struct into its own file. This change is made to avoid further expanding the GUI dependencies on `wallet.h`. Structurally, the GUI should only access the model/interfaces and never the wallet directly.

fa6801366d refactor: [rpc] Remove confusing and brittle integral casts (take 2) (MarcoFalke)

Pull request description:

  Second take for cases which I seem to have missed in commit 94ddc2dced.

  When constructing an UniValue from integral values, historically (long ago), in some cases casts where needed. With the current UniValue constructor, only very few are actually needed.

  Keeping the unused casts around is:

  * confusing, because code readers do not understand why they are needed
  * brittle, because some may copy them into new places, where they will lead to hard-to-find logic bugs, such as the ones fixed in pull https://github.com/bitcoin/bitcoin/pull/34112

  So fix all issues by removing them, except for a few cases, where casting was required:
  * `static_cast<bool>(fCoinBase)`, because `bool{fCoinBase}` only works on modern compilers.

  This hardening refactor does not fix any bugs and does not change any behavior.

Pull request description:

  picks up https://github.com/bitcoin/bitcoin/pull/25269.

  This PR re-implements the code path so that an error message is thrown when a transaction's total amount (including fees) exceeds the available balance. It also refactors the wallet's coin selection code.

  1. the first 3 commits are unrelated to the code but few small bug fixes which are nice to fix. but also kind of impacts the remaining logic. (could PR separately if reviewers wish)
  1. c467325aaf187d7f056bb1ea1cec6b7c4250af2e: make `total_effective_amount` optional actually optional
  2. 2202ab597596c84fc49f8784e823372b7a9efcbe: ensure `set<shared_ptr<COutput>>` has unique COutput
  3. a5ffbbf122d66fc4ad9b2e7c6d7d1dfa1816388e: Correctly reserve size when flattening `CoinsResult.coins` map to vector

  3. the next 3 commits from 4745d5480ca5c3809edd51140e4d2c0433582844 replace the `PreSelectedInputs` struct with `CoinsResult` and removes `PreSelectedInputs`.

  4. the last commit (e664484a6d34c1795ebb0925ab31faea5d64ab00) deals with the error message - `AmountWithFeeExceedsBalance` error inside `WalletModel::prepareTransaction` is never thrown and remains an unused code path. This is because `createTransaction` does not retrieve the fee when the process fails. The fee return arg is set only at the end of the process, when the transaction is successfully created. Therefore, if the transaction creation fails, the fee is not available inside `WalletModel::prepareTransaction` to trigger the `AmountWithFeeExceedsBalance` error.

  This PR re-implements the feature inside `CreateTransactionInternal` and adds test coverage for it.

7819da2c16 walllet: use CoinsResult instead of PreSelectedInputs
PreSelectedInputs is confusing to use. it's `total_amount`
might store total amount or effective amount based on SFFO.
ex: we might accidentally sum preselected inputs effective
amount (named `total_amount`) with automatically selected
inputs actual total amount.

CoinsResult has a cleaner interface with separate fields
for both these amounts.

2 behavioural changes:

1. no more default assert error if effective value is unset
    - previously PreSelectedInputs::Insert() called
      COutput::GetEffectiveValue() which assert failed
      if the optional was unset.
    - now we don't default assert anymore.
      * in GUI/getAvailableBalance better not to assert.
      * SelectCoins's preselected inputs always contain a
        feerate, so effective amount should be set.
        explicitly added an assertion to ensure this.

2. FetchSelectedInputs uses OutputType::UNKNOWN as key to
   populate CoinsResult's coins map. it's discarded later.

fa0677d131 refactor: Use SpanReader over DataStream
This refactor does not change behavior. However, it avoids a vector
copy, which can lead to a minimal speed-up of 1%-5%, depending on the
call-site. This is mostly relevant for the fuzz tests and utils that

was called.

7072d825e3 wallet: ensure COutput added in set are unique
before #25806, set<COutput> was used and would not
contain same COutputs in the set.

now we use set<shared_ptr<COutput>> and it might be
possible for 2 distinct shared_ptr (different pointer
address but same COutputs) to be added into the set.

so preserve previous behaviour by making sure values
in the set are also distinct

f0a046094e scripted-diff: refactor: CWallet::LoadWallet->PopulateWalletFromDB (David Gumberg)

Pull request description:

  This PR is mostly a refactor which splits out logic used for creating wallets and for loading wallets, both of which are presently contained in `CWallet::Create()` into `CWallet::CreateNew()` and `CWallet::LoadExisting()`

  The real win of this PR is that `CWallet::Create()` uses a very bad heuristic for trying to guess whether or not it is supposed to be creating a new wallet or loading an existing wallet:

  370c592612/src/wallet/wallet.cpp (L2882-L2885)

  This heuristic assumes that wallets with no `ScriptPubKeyMans` are being created, which sounds reasonable, but as demonstrated in #32112 and #32111, this can happen when the user tries to load a wallet file that is corrupted, both issues are fixed by this PR and any other misbehavior for wallet files which succeeded the broken heuristic's sniff test for new wallets.

  It was already the case that every caller of `CWallet::Create()` knows whether it is creating a wallet or loading one, so we can avoid replacing this bad heuristic with another one, and just shift the burden to the caller.

b189a34557 test: add case where `TOTAL_TRIES` is exceeded yet solution remains (yancy)

Pull request description:

  Show that `CoinGrider` halts searching when the number of attempts exceeds `TOTAL_TRIES`.  To do so, show that a solution is found, then add one more entry to the same set of inputs.  Since the search orders by `effective_value`, the solution is constructed such that only values with the lowest `effective_value` have the least weight.  Only the lowest weight values will not exceed the `max_selection_weight`. Therefore, `CoinGrinder` will not evaluate all lowest weight solutions together before exceeding `TOTAL_TRIES` since they are last found.

  This test case was inspired by a similar test for `BnB` currently named `bnb_test`.

516be10bb5 wallet: Rename RecordType::DELETE to RecordType::DELETE_FLAG
On Windows, the `winnt.h` header defines `DELETE` as a macro for a
"Standard Access Right" bitmask (0x00010000L).

This introduces a fragile dependency on header inclusion order: if
Windows headers happen to be included before this enum definition,
the preprocessor expands `DELETE` into a numeric literal, causing
syntax errors.

Rename the enumerator to `DELETE_FLAG` to remove this fragility and
avoid the collision entirely.

fad042235b refactor: Remove remaining std::bind, check via clang-tidy (MarcoFalke)

Pull request description:

  `std::bind` has many issues:

  * It is verbose in a meaningless way
  * Overriden args are silently accepted and dropped at runtime without a compile error. Same for accidental duplicates.

  One could use `std::bind_front` similar to commit fa267551c4. Though, I think the remaining cases are better off with lambdas.

  So do that here, and enable the `modernize-avoid-bind` clang-tidy rule to avoid `std::bind` bugs in the future.

Pull request description:

  `removeprunedfunds` removes all entries from `mapTxSpends` for the inputs of the pruned tx. However, this is incorrect, because there could be multiple entries from conflicting transactions (that shouldn't be removed as well). This could lead to the wallet creating invalid transactions, trying to double spend utxos.
  The bug persists when the conflicting tx was mined, because the wallet trusts its internal accounting instead of calling `AddToSpends` again.

  The added test should fail on master.

fab2f3df4b fuzz: Exclude too expensive inputs in descriptor_parse targets (MarcoFalke)

Pull request description:

  Accepting "expensive" fuzz inputs which have no real use-case is problematic, because it prevents the fuzz engine from spending time on the next useful fuzz input.

  For example, those will take several seconds (!) and the flamegraph shows that base58 encoding is the cause:

  ```
  curl -fLO 'f5abf41608'
  curl -fLO '78cb317546'

  FUZZ=mocked_descriptor_parse ./bld-cmake/bin/fuzz ./f5abf41608addcef3538da61d8096c2050235032
  FUZZ=descriptor_parse ./bld-cmake/bin/fuzz ./78cb3175467f53b467b949883ee6072e92dbb267
  ```

  This will also break 32-bit fuzzing, see https://github.com/bitcoin/bitcoin/issues/34110#issuecomment-3759461248.

Writing the wallet's `CLIENT_VERSION` (which indicates the last version

wallet loading.

The next commit removes the `PopulateWalletFromDatabase()` call from
wallet creation, but this behavior needs to be preserved, so this commit
factors setting `CLIENT_VERSION` out of `PopulateWalletFromDatabase()`
so that wallet creation can use it in the next commit.
