Native review finding status atomicity

The task review repository is the owner of persisted finding state. A status transition updates status and resolved_at in one database statement and returns the row produced by that statement. The service validates the requested status before it calls the repository, then publishes the existing finding updated event with the returned row.

Concurrent writers can therefore observe different final rows without creating a timestamp that describes an earlier read. SQLite tests provide deterministic coverage. A PostgreSQL test with two database connections checks the same transaction boundary when a PostgreSQL environment is available.
