Add CI integration/E2E jobs, Vercel cron DB reset, and test fixes

- CI: add integration test job with PostgreSQL service container
- CI: add E2E test job with DB seed and Playwright
- Add /api/cron/reset endpoint for hourly demo DB reset (Vercel Cron)
- Extract seed logic to shared seed-data.ts (CLI + API)
- E2E: auto-reseed in global-setup to prevent stale password state
- E2E: fix status/priority change tests (waitForResponse instead of timeout)
- Fix dashboard test quote mismatch ('customer' vs "customer")
