1823766 refactor: add thread safety lock assertion to WriteBlockIndexDB() (Jon Atack) Pull request description: New helper function `BlockManager::WriteBlockIndexDB()` added in bitcoin#23974 has a thread safety lock annotation in its declaration but is missing the corresponding run-time lock assertion in its definition. Per doc/developer-notes.md: "Combine annotations in function declarations with run-time asserts in function definitions."
