🔧 Implement deployment fixes and enhance Gitea workflows

- Created `DEPLOYMENT-FIXES.md` to document issues and solutions for Gitea Actions.
- Fixed Dockerfile path for standalone build.
- Enhanced `gitea-deploy.sh` with improved environment variable handling and extended health check timeouts.
- Introduced `gitea-deploy-simple.sh` for simplified deployments without database dependencies.
- Updated Next.js configuration to resolve build issues.
- Improved health check logic and error handling across all Gitea workflows.

✅ These changes enhance deployment reliability and provide better debugging information.
