ci: add Gitea Actions workflows (CI/deploy + weekly npm audit)

- ci.yml: run Playwright tests on every push to main, then deploy to VPS
  if tests pass; includes post-deploy health check
- audit.yml: weekly npm audit (Mondays 07:00 UTC), fails on high/critical
- Requires VPS_SSH_KEY secret (already configured in repo settings)
