Make debug-migration GET a robust pgvector/migration diagnostic

Browse source 
Each probe now runs independently (pgvector check first and standalone) and
reads the drizzle journal from the correct "drizzle" schema, so the endpoint
returns a usable diagnostic instead of crashing on the first missing relation.
Also reports whether error_events exists.
