- Simplified init_db() to only call Base.metadata.create_all() on all
three engines — no more _ensure_*() inline additive migrations
- run_alembic_migrations() now raises on failure (no safety net to
fall back to)
- All schema changes (add/drop/rename columns, data migrations) must
go through Alembic. create_all() handles new tables only.
@REJECTED _ensure_*() inline migrations removed because they:
- Duplicated Alembic logic without versioning
- Created hidden schema drift (columns existed in DB but had no
corresponding Alembic migration)
- Made audits and fresh DB provisioning unreliable
