feat: update pg_cron migration — rename daily-cron→youtube-stats, handle existing jobs

- Unschedules existing jobs (daily-cron, daily-content-ingest) before creating new ones
- Renames daily-cron to youtube-stats (same schedule: midnight UTC, same /api/cron endpoint)
- Replaces daily-content-ingest with ingest-daily (10am UTC)
- Updates check-renders from every 2min to every 5min
- All unschedules wrapped in DO blocks for idempotent re-runs
- Uses current_setting('app.cron_secret') for auth headers
