fix: switch Docker registry to HTTPS endpoint with login-action

- Replace gitea-http.gitea.svc.cluster.local:3000 with registry.lab.daviestechlabs.io
- Use docker/login-action@v3 for Gitea registry auth (proper buildx integration)
- Remove manual base64 auth to ~/.docker/config.json (not picked up by buildkit)
- Remove insecure registry daemon.json config and Docker restart
- Remove buildkitd insecure registry config
- Remove cache-from/cache-to type=gha (not supported on Gitea Actions)

Fixes 401 Unauthorized: reqPackageAccess on Docker push
