Add CI/CD: Gitea Actions workflows + Act Runner

- .gitea/workflows/test.yml: unit tests + build on every push
- .gitea/workflows/deploy.yml: auto deploy to production on push to main
- .gitea/workflows/preview.yml: PR preview environments at pr-{id}.oil.oci.euphon.net
  - Bakes production DB copy into preview image (no PVC needed)
  - Auto-creates namespace + deployment + ingress with TLS
  - Comments PR with preview URL
  - Tears down on PR close
- scripts/setup-runner.sh: act_runner installation script

Runner: hera-runner (host mode, ubuntu-latest label)
