Make project page/navigation construction more consistent, particularly on mobile

Summary: Ref T10054. This mostly makes sure that mobile gets to have the same profile menu that Desktop does.

Test Plan:
  - Viewed menus on mobile, saw all profile menu actions available.
  - Viewed/used changed pages (column detail, edit column, edit picture).
