FEATURE: Improve Culling Support

[Flohhhhh]

Feature Description

I think overall culling is not really well supported at the moment.

1. The existing automated culling tool is a bit restrictive and hard to use. (Also quite hidden)
2. "Rejection" only exists as a name for assigning Red color label in the automated culling tool, nowhere else
3. It's not very easy to batch move files into different folders

I would propose:

1. Add rejection as a first class feature using a rating value of -1 (Same as Lightroom/Adobe ecosystem) and allow X or other hotkey as a way to toggle this quickly on a selected/focused image
2. Fade out rejected images for clarity
3. Add rejected filter in the Library filters
4. Add a way to batch select files in current directory based on rejection status, rating, color label, etc.
5. During folder creation, add an option to move selected files to the folder
6. Brand the current "culling" implementation as something that's explicitly automated, as culling is something that is the concept of pruning unwanted photos, not just automated processes.

I'm still thinking more about this, would be happy to discuss with anyone!

I'm mostly familiar with the UX in Lightroom which is admittedly pretty dated itself, so I feel there could be better ways to approach this. Luckily the standard viewport changes images pretty quickly so a separate culling view/flow is not needed. Usually I reject any images I don't want, then select all un-rejected images, and move them to a separate "selects" folder to start editing. It would be nice to be able to do this, but I know other people have different systems and needs, maybe there's a better way!

First part of this was implemented in my PR #1075

Still need to address file management stuff separately

1. Better ability to move files around folders (drag currently not an option)
2. Option to move selected folders to a file on creation
3. Other file management improvements

This stuff would pair nicely with the batch selection features implemented.
