fix: add nginx SPA fallback

- Replace GITEA_PASSWORD with GITEA_TOKEN in environment variables
- Add validation checks for GITEA_USERNAME and GITEA_TOKEN
- Update git remote URL to include token for authentication
- Simplify push command to use configured origin remote

This change enhances security by using a token instead of a password for Git authentication in the CI pipeline.
