feat: enhance Media Library filtering and sorting

- Add sort functionality (newest, oldest, name A-Z/Z-A, size)
- Update media type filters: Images (JPG/PNG), Videos (MP4/MOV/GIF), Audio, Vectors (SVG)
- Replace photography filter with 'Published in' filter (Photos/Universe/Unpublished)
- Fix API to properly handle JSON array queries with array_contains
- Add comprehensive WHERE clause building for multiple filters
