Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@src/test/util/setup_common.cpp`:
- Around line 404-409: Reorder teardown in the setup cleanup sequence so
m_node.mempool->DisconnectManagers() executes before m_node.llmq_ctx.reset().
Preserve the existing chain_helper and dmnman cleanup behavior, changing only
the ordering needed to disconnect mempool managers while the InstantSend/LLMQ
context remains valid.

Outside diff comments:
In `@src/init.cpp`:
- Around line 2095-2104: Before setting fReindex in the retry path around the
failed load check in src/init.cpp lines 2095-2104, tear down the existing
chainstate resource graph so the loop can safely recreate node.mempool and
node.chainman. In src/node/chainstate.cpp lines 47-82, update the replacement
cleanup order to release chain_helper, the mempool connection, llmq_ctx, dmnman,
and evodb in reverse dependency order before destroying dependents.

Nitpick comments:
In `@src/test/util/setup_common.cpp`:
- Around line 328-330: Update the LogPrintf call in the VerifyLoadedChainstate
callback within LoadVerifyActivateChainstate to use the enclosing function name
explicitly instead of __func__. Preserve the existing bls_state value and log
format.

In `@src/test/validation_chainstatemanager_tests.cpp`:
- Around line 53-54: Correct the misspelled “chain_helpper” in the
initialization comment above node.chain_helper.reset() to “chain_helper”.

In `src/node/chainstate.cpp`:
- [BLOCKING] src/node/chainstate.cpp:78-80: Fold the build-restoring chainstate changes into the refactor
  Commit 171e0361b95 inlines DashChainstateSetup into LoadChainstate but passes the undeclared identifiers dash_dbs_in_memory, fReset, fReindexChainState, bls_threads, worker_count, max_recsigs_age, and mempool. Commit 4a49ad20725 later replaces them with ChainstateLoadOptions members, confirming that 171e0361b95 cannot compile independently. Fold those build-restoring changes into the refactor so every permanent commit remains buildable and usable for bisecting.

In `src/bitcoin-chainstate.cpp`:
- [SUGGESTION] src/bitcoin-chainstate.cpp:110-118: Incorrect transformation: dash-chainstate option values are not preserved
  Before this range, dash-chainstate explicitly set bls_threads, worker_count, and max_recsigs_age to 1, preserving the arguments used before the bitcoin#25308 parameter-to-options refactor. This change removes those assignments and inherits defaults of 0 BLS-check threads, a hardware-dependent worker count between 1 and 4, and a recovered-signature age of 604800 seconds. That changes the executable's behavior even though the backport only requires changing how the values are passed. Keep the three explicit values unless this behavioral change is proposed and justified separately.

In `src/bitcoin-chainstate.cpp`:
- [SUGGESTION] src/bitcoin-chainstate.cpp:109-116: Preserve dash-chainstate option values through the refactor
  Before bitcoin#25308, this executable passed `1` for `bls_threads`, `worker_count`, and `max_recsigs_age`; the original Dash backport preserved those values as explicit `ChainstateLoadOptions` assignments. This PR removes them, causing the executable to inherit `DEFAULT_BLSCHECK_THREADS` (`0`), a hardware-dependent worker count from 1 to 4, and `DEFAULT_MAX_RECOVERED_SIGS_AGE` (`604800`). That is a behavior change hidden inside a parameter-to-options follow-up. Restore the explicit values unless the behavior change is proposed and justified separately.
