Ewald b700149b2d feat: Enhance metadata handling and fallback mechanisms
- Introduced fallback readers for metadata extraction when ExifTool/ffprobe are unavailable, utilizing Pillow and hachoir for images and media files respectively.
- Added settings for metadata fallback preferences, allowing users to toggle image and media fallback options.
- Implemented route collision logging to prevent overlapping API paths.
- Added middleware for authentication on sensitive routes, ensuring secure access.
- Updated API documentation to reflect new endpoints and settings.
- Enhanced unit tests for metadata handling, case sensitivity in file paths, and fallback mechanisms.
- Removed compatibility shims for shared modules, consolidating imports under mjr_am_shared.
