feat: Add photo_media_type field to API responses and enhance media handling in frontend

This commit introduces a new `photo_media_type` field in the `PendingLinkageResponse` and `ReportedPhotoResponse` interfaces, allowing differentiation between image and video files. The frontend has been updated to handle video links appropriately, including opening video files directly and displaying video thumbnails. Additionally, the search functionality has been enhanced to exclude videos when searching for "Photos without faces." Documentation has been updated to reflect these changes.
