This commit introduces several enhancements related to video management, including the addition of a new API for handling video-person identifications. The frontend has been updated to support video listing, person identification in videos, and the ability to remove person identifications. A new database table, photo_person_linkage, has been created to manage the relationships between videos and identified persons. Additionally, video thumbnail generation has been implemented, improving the user experience when interacting with video content. Documentation has been updated to reflect these changes.
