fix(compose): separate meta DBs for Metabase and Directus; replace NocoDB with Directus

- Metabase metadata → metabase_meta DB (was: shared bit_flight_deck.public, caused conflicts)
- NocoDB removed (Community Edition requires Enterprise plan for external PostgreSQL sources)
- Directus added → directus_meta DB (open-source, works with PG as source DB out of the box)
- Both metabase_user and directus_user get read access to bit_flight_deck schemas
- directus_user gets RW on core.identity_map, core.deal_team_member, core.employee
