- Rename portfolio_items migration to run before application_portfolio_items pivot
- Fix materialized view referencing cp.niches (should be cp.content_niches) and remove nonexistent last_active_at column
- Make entrypoint non-fatal on migration failure with DB wait loop
- Health endpoint always returns 200 (degraded status in body) to prevent Docker killing healthy containers
