feat: add launch command for switching avatars (#1145)

* feat: add launch command for switching avatars

* fix: reuse selectAvatarWithoutConfirmation

* chore: remove FIXME comments

* fix: address comments

- ipcEvent does not need to be async
- use $app instead of $app.methods

* fix: consolidate settings option

Instead of having two settings to control focus and confirmation
seperately, just use one and grab focus when its enabled.
