fix(ci): remove obsolete Node.js setup, use Gitea-compatible syntax

- Remove Node.js installation (frontend is now static Qute/Alpine)
- Remove src/frontend/node_modules cache (no longer exists)
- Change github.workflow to gitea.workflow for Gitea Actions compatibility
- Increase container memory from 8g to 10g for native builds
- Add BUILDKIT_INLINE_CACHE=1 for faster Docker builds
