Fix Gitea repo search: correct service name and add UI support

- GITEA_URL was pointing to gitea.platform.svc but the Helm chart
  names the HTTP service gitea-helm-http.platform.svc
- Add Gitea badge (GT, green) to repo search results UI
- Update placeholder and credential hint to mention Gitea
- Rewrite internal service URLs to external gitea.coreworlds.io in
  search results so agents can clone from outside the cluster
- Add error logging to diagnose search failures
