fix: CI/CD workflow for Gitea Actions - use proper authentication and fix checkout issues

Updated workflow to:
- Use Gitea token for repository checkout authentication
- Use Gitea repository owner as username for registry login
- Use PACKAGES_TOKEN secret for registry authentication
- Follow proven pattern from working repository
- Only build and push on main/master branches and version tags
- Added proper job dependencies (test → build → docker)
