Hotkey recording in Settings Window

[memohnsen]

This PR references a discord conversation about adding hotkey recording support in the Settings UI for both toggle the view and opening the clipboard history. This PR also cleans up a clippy error from the settings UI change that had dead code for reset fields no longer in use.

New Behavior

• Tapping on the hotkey text field starts recording key presses
• Esc ends recording and saves new config
• At least one modifier key is required
• Keybindings cannot be the same as others used within Rustcast
• Keybindings are written to config file same style as before, no breaking changes

I think the code is ok, just that maybe it should also be applicable to the shell commands hotkeys

[memohnsen]

added and merge conflicts fixed

I've reviewed the code.. I'll try out the implementation and then I'll approve

Maybe we should consider using a custom widget so that we can simply add this to the commands tab as well.

Seems to work as intended, but the only issue is, i've noticed that when i change something in the settings, the hotkeys stop working. Can that be fixed?
