Allow users to add "ProfileMenu" items on mobile

Summary:
Depends on D20337. Fixes T12167. Ref T13272. On this page ("Favorites > Edit Favorites > Personal", for example) the curtain actions aren't available on mobile.

Normally, curtains are built with `Controller->newCurtainView()`, which sets an ID on the action list, which populates the header button. This curtain is built directly because there's no `Controller` handy.

To fix the issue, just set an ID. This could probably be cleaner, but that's likely a much more involved change.

Test Plan: Edited my favorites, narrowed the window, saw an "Actions" button.
