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.
See:
```

Since we no longer delete the wallet directory, there's no need to vacate it
The moving only served to risk errors by crossing filesystem boundaries (which fs::rename can't handle)
If any other files exist in the directory, we cannot assume the sharable files are exclusively for this wallet.
But if they are, this also cleans up other log.* files
Instead of checking whether the total amount of inputs known by the
wallet is greater than 0, we should be checking for whether the input is
known by the wallet. This enables us to determine whether a transaction
spends an of output with an amount of 0, which is necessary for marking
0-value dust outputs as spent.

Because the default wallet has no name, the watch-only and solvables
wallets created during migration end up having no name either.
This fixes it by applying the same prefix name we use for the backup
file for an unnamed default wallet.
Before: watch-only wallet named "_watchonly"
After: watch-only wallet named "default_wallet_watchonly"

Right now, after migration the last message users see is "migration completed",
but the migration isn't actually finished yet. We still need to load the new wallets
to ensure consistency, and if that fails, the migration will be rolled back. This
can be confusing for users.
This change logs the post-migration loading step and if a wallet fails to load and
the migration will be rolled back.

When migrating any legacy unnamed wallet, a failed migration would
cause the cleanup logic to remove its parent directory. Since this
type of legacy wallet lives directly in the main '/wallets/' folder,
this resulted in unintentionally erasing all wallets, including the
backup file.
To be fully safe, we will no longer call `fs::remove_all`. Instead,
we only erase the individual db files we have created, leaving
everything else intact. The created wallets parent directories are
erased only if they are empty.
As part of this last change, `RestoreWallet` was modified to allow
an existing directory as the destination, since we no longer remove
the original wallet directory (we only remove the files we created
inside it). This also fixes the restore of top-level default wallets
during failures, which were failing due to the directory existence
check that always returns true for the /wallets/ directory.
This bug started after:
f6ee59b6e2
Previously, the `fs::copy_file` call was failing for top-level wallets,
which prevented the `fs::remove_all` call from being reached.

Track what RestoreWallet creates so only those files and directories
are removed during a failure and nothing else. Preexisting paths
must be left untouched.
Note:
Using fs::remove_all() instead of fs::remove() in RestoreWallet does
not cause any problems currently, but the change is necessary for the
next commit which extends RestoreWallet to work with existing directories,
which may contain files that must not be deleted.

Previously, we would check failing input scripts twice when considering
a transaction for the mempool, in order to distinguish policy failures
from consensus failures. This allowed us both to provide a different
error message and to discourage peers for consensus failures. Because we
are no longer discouraging peers for consensus failures during tx relay,
and because checking a script can be expensive, only do this once.
Also renames non-mandatory-script-verify-flag error to
mempool-script-verify-flag-failed.

Do not discourage nodes even when they send us consensus invalid
transactions.
Because we do not discourage nodes for transactions we consider
non-standard, we don't get any DoS protection from this check in
adversarial scenarios, so remove the check entirely both to simplify the
code and reduce the risk of splitting the network due to changes in tx
relay policy.

Since it was introduced in 4eb515574e (#18044), the detection of a
stripped witness relies on running the Script checks 3 times. In the worst case, this consists in
running Script validation 3 times for every single input.
Detection of a stripped witness is necessary because in this case wtxid==txid, and the transaction's
wtxid must not be added to the reject filter or it could allow a malicious peer to interfere with
txid-based orphan resolution as used in 1p1c package relay.
However it is not necessary to run Script validation to detect a stripped witness (much less so
doing it 3 times in a row). There are 3 types of witness program: defined program types (Taproot,
P2WPKH, P2WSH), undefined types, and the Pay-to-anchor carve-out.
For defined program types, Script validation with an empty witness will always fail (by consensus).
For undefined program types, Script validation is always going to fail regardless of the witness (by
standardness). For P2A, an empty witness is never going to lead to a failure.
Therefore it holds that we can always detect a stripped witness without re-running Script validation.
However this might lead to more "false positives" (cases where we return witness stripping for an
otherwise invalid transaction) than the existing implementation. For instance a transaction with one
P2PKH input with an invalid signature and one P2WPKH input with its witness stripped. The existing
implementation would treat it as consensus invalid while the implementation in this commit would
always consider it witness stripped.

Not enforcing TRUC topology on reorg was the intended
behavior, but the appropriate bypass argument was not
checked.
This mistake means we could potentially invalidate a long
chain of perfectly incentive-compatible transactions that
were made historically, including subsequent non-TRUC
transactions, all of which may have been very high feerate.
Lastly, it wastes CPU cycles doing topology checks since
this behavior cannot actually enforce the topology in
general for the reorg setting.

Since #29412, we have not allowed mutated blocks to continue

is only done for the legacy BLOCK message.
Extend these checks as belt-and-suspenders to not allow
similar mutation strategies to affect relay by honest peers
by applying the check inside
PartiallyDownloadedBlock::FillBlock, immediately before
returning READ_STATUS_OK.
This also removes the extraneous CheckBlock call.

The committed state of an index should never
be ahead of the flushed chainstate. Otherwise, in the case
of an unclean shutdown, the blocks necessary to revert
from the prematurely committed state would not be
available, which would corrupt the coinstatsindex in particular.

Let's say an attacker wants to use/exhaust the network's bandwidth, and
has the choice between renting resources from a commercial provider and
getting the network to "spam" itself it by sending unconfirmed
transactions. We'd like the latter to be more expensive than the former.
The bandwidth for relaying a transaction across the network is roughly
its serialized size (plus relay overhead) x number of nodes. A 1000vB
transaction is 1000-4000B serialized. With 100k nodes, that's 0.1-0.4GB
If the going rate for commercial services is 10c/GB, that's like 1-4c per kvB
of transaction data, so a 1000vB transaction should pay at least $0.04.
At a price of 120k USD/BTC, 100sat is about $0.12. This price allows us
to tolerate a large decrease in the conversion rate or increase in the
number of nodes.

Back when we implemented coin age priority as a miner policy, miners
mempools might admit transactions paying very low fees, but then want to
set a higher fee for block inclusion. However, since coin age priority
was removed in v0.15, the block assembly policy is solely based on fees,
so we do not need to apply minimum feerate rules in multiple places. In
fact, the block assembly policy ignoring transactions that are added to
the mempool is likely undesirable as we waste resources accepting and
storing this transaction.
Instead, rely on mempool policy to enforce a minimum entry feerate to
the mempool (minrelaytxfee). Set the minimum block feerate to the
minimum non-zero amount (1sat/kvB) so it collects everything it finds in
mempool into the block.
