Module event_handler 

Engine event handler: persists EngineMessage variants to Postgres.

This module contains the core event-to-SQL logic that was previously embedded in the root crate’s DieselEventHandler. It operates on a bare &mut PgConnection so callers can wrap calls in their own transactions.
