fix: remove Kamal deploy job (no server configured), force Node.js 24 in CI

- Removed deploy-production job — Kamal config has placeholder IPs, no secrets
- Renamed workflow to "Build & Push" — test + Docker image to GHCR
- Added FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true to suppress Node.js 20 warnings
