🔧 Improve health check logic in Gitea workflows

- Enhanced health check mechanisms in `ci-cd-fast.yml` and `ci-cd-zero-downtime-fixed.yml` to utilize `docker exec` for internal checks, addressing issues with direct port access.
- Updated health check logic to provide better error messages and fallback methods, ensuring more reliable deployment verification.
- Documented changes in `DEPLOYMENT-FIXES.md` to reflect improvements in health check processes.

✅ These updates enhance the reliability of health checks during deployments and improve debugging capabilities.

+#### **6. ✅ Fixed Health Check Logic**
+- **Issue**: Health checks timing out even though applications were running correctly
+- **Root Cause**: Workflows trying to access `localhost:3000` directly, but containers don't expose port 3000 to host
+- **Fix**: Updated health check logic to:
+  - Use `docker exec` for internal container health checks
+  - Check nginx proxy endpoints (`localhost/api/health`) for zero-downtime deployments
+  - Provide fallback health check methods
+  - Better error messages and debugging information
