🔧 Make health checks more robust with detailed debugging

🔍 Enhanced Debugging:
- Show HTTP response codes and response bodies
- Remove -f flag that was causing curl to fail on valid responses
- Add detailed logging for each endpoint test
- Show container logs on failures

🌐 Improved Health Check Logic:
- Check HTTP code = 200 AND response body exists
- Use curl -w to capture HTTP status codes
- Parse response and status separately
- More tolerant of response format variations

🧪 Better API Endpoint Testing:
- Test each endpoint individually with status reporting
- Show specific HTTP codes for each endpoint
- Clear success/failure messages per endpoint
- Exit only on actual HTTP errors

🎯 Addresses CI-Specific Issues:
- Local testing shows endpoints work correctly
- CI environment may have different curl behavior
- More detailed output will help identify root cause
- Removes false failures from -f flag sensitivity

 Should resolve curl failures despite HTTP 200 responses
