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.
