feat: Add filter options for file types; is_edited

Just thought that this is a nice filter to have since sometimes when importing files it contains both JPEG and raws.

Thanks for the PR, @ALPHAAAL! These are very useful filter additions 💯

I've noticed a technical issue with the 'edited/unedited' filter. The is_edited status is only determined when the folder is first loaded and doesn't update when a user makes or resets edits. This causes the filter to become inaccurate.

For that reason, I'll be removing the edited/unedited filter for now. The RAW / Non-RAW filtering is a solid addition, and I'll merge that part of the change.

If you can find a good solution for updating the is_edited state accurate, I'd be happy to review and merge that functionality as well.

P.S. I also updated the has_sidecar_adjustments check in the backend. I'm leaving this improved functionality in place as it will be useful for future filtering.

Thanks again for the contribution :)
