feat(map-editor): menu-bar top-level labels render + click

Browse Source 
Adds the seven category labels (File, Edit, View, Map, Tools,
Window, Help) at the top of the screen with hover highlight and
click-to-open / click-to-close behaviour. Item arrays are still
empty stubs; dropdown rendering lands in the next slice.
