Kurt 2c541ad422
Update to .NET 10 (#4676)
* Update to .NET 10
* Property fields
* API signature updates
* Extension method blocks

* Completed dark mode support
  Outside of my control:
- vertical tab control (pkm editor)
- datetimepicker controls
- lgpe event flags (no idea)
- some control types having white-borders when they should really be gray

Box background is 50% transparency to effectively darken the image.

* Custom legality report popup
* Event diff dialog, version select dialog
* Add quick overwrite popup for export sav
* Extension methods
* Dark Mode: glow currently editing sprite
* Add invalid encounter hint for trade evolutions
* Extension properties
* Append legality hint on hover card
* Slot image loading: clear the screen-reader description if a slot is empty/invalid, rather than retain the previous description. Changing boxes would easily confuse users on this.
