Fix Shortcut Key

[maiko3tattun]

Fixes:

• Fixed an issue where modifier keys were swapped on macOS
  • On macOS, the process changes only when reading from or writing to files.
• Fixed an issue where shortcut keys were not displayed in the menu on macOS
  • InputGesture must be bound to a KeyGesture class or a string that can be parsed into one.

Behavior Changes:

• Support for multiple shortcut keys
  • I didn't want to make this feature too complicated, but not being able to use Ctrl+Shift+Z to redo would really hurt the user experience.
• Save only the changes, rather than all key mappings
  • If we don't make this change, existing users will no longer be able to use the new shortcuts when new features are added in the future.

In Progress:

• ✅ Key assignment flow (currently creating a separate dialog)
• ✅ Reading and writing key mappings for External Batch Edit
• ✅ Reading and writing key mappings for legacy plugins (may not be implemented if there are conflicts with the original shortcut key system)
• ✅ Set key assignments to “None”
• ✅ Also supports remapped keys in the main window
