feat: Enhance logging and error handling for job streaming and photo uploads

- Added new logging scripts for quick access to service logs and troubleshooting.
- Updated job streaming API to support authentication via query parameters for EventSource.
- Improved photo upload process to capture and validate EXIF dates and original modification times.
- Enhanced error handling for file uploads and EXIF extraction failures.
- Introduced new configuration options in ecosystem.config.js to prevent infinite crash loops.
