Polish OpenSettings action for Settings UI and Profile page navigation on refresh (#8670)

Performs a number of minor bugfixes related to the Settings UI:
- b5370a1 Dropdown bug:
  - the dropdown would display the keybinding for the first
    `openSettings` found. So it would accidentally present and bind the
    one for the Settings UI.
- 91eb49e autogenerated name for opening Settings UI:
  - the Settings UI keybinding would display "open settings file". This
    was updated to say "Open Settings UI".
- 1cadbf4 Profile Page navigation crash:
  - the selected item off of a MUX navigation view returns a MUX
    NavViewItem (as opposed to WUX)
-  dd2f3e5 Hookup delete for Profile page navigation:
   - missed a spot where we were manually navigating to the Profile
     page. So it wasn't hooked up properly
- 9fea6de Properly cast NavViewItem tags
  - When we update the NavigationView's menu items, we were casting the
    tags to `Model::Profile` instead of `Editor::ProfileViewModel`.

#6800 - Settings UI epic

Fixes the following bug:
> - [ ] JSON change --> crash
>   - open SUI --> open JSON --> edit retro effects in JSON --> save file --> cry because the app crashed

## Additional comments
This was a part of some manual testing I performed on the Settings UI.
More intricate bugs are being reported on #6800 and will be fixed in
their own PR.
