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.
