Web-App - Endpoints Needed for parity with other apps

[strazto]

Environment

• OS: Any
• Distribution: WebApp

Endpoints

• [x] Duplicates
  • [x] View thumbs ( #7 )
  • [ ] Manipulate (Delete, merge, move, etc)
• [ ] Scan
  • [ ] Pause
  • [ ] Better scan status updates
• [ ] Better error communication
  • [ ] Eg, missing ffmpeg/ffprobe dependencies
  • Probably involves improving exception handling on engine
• [ ] Database manipulation
  • [ ] Import, export, clean

In fairness, database exploration is pretty buggy on native frontends anyway

duplicate api notes:

I've been considering how to provide some consistent API view for manipulating duplicates, as the current GET just fetches them by whatever order they show up in the list.

I think the best approach is probably to return a view of them grouped by GroupId, which can be transformed client-side (though, most likely, it's the most useful view anyway), and itemized API requested can be done through /api/duplicate/{gid}/{index_in_group}/ (? maybe - though index_in_group still feels unstable if multiple clients were connected) so possibly /api/duplicate/{gid}/{hash(path)}/.
