fix(gui): Re-enable application menu (#1888)

* fix(gui): Re-enable application menu

This re-enables the application menu to allow for OS native shortcuts
to work again (i.e. hide/minimize window), which also allows us to
get rid of the global-shortcuts hack to prevent window reloads.

Change-Type: patch
Changelog-Entry: Fix disabled native OS window shortcuts

* refactor(gui): Update kbd shortcut comment to be less specific
