Subject: [PATCH] fix(db): add rollback on exception in get_db dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prevents InFailedSQLTransaction cascade — when a request fails mid-
transaction, the connection is rolled back before being returned to
the pool, so subsequent requests on the same connection don't inherit
a poisoned transaction state.
