Dayron e3dad39c4f feat: Add TripImageService for automatic trip image management
- Implemented TripImageService to load missing images for trips, reload images, and clean up unused images.
- Added functionality to get image statistics and clean up duplicate images.
- Created utility scripts for manual image cleanup and diagnostics in Firebase Storage.
- Introduced tests for image loading optimization and photo quality algorithms.
- Updated dependencies in pubspec.yaml and pubspec.lock for image handling.
