feat: restaurant cover photo upload

restaurants.cover_url existed in the schema and was already read by the
public menu page, but nothing could ever write it — the update endpoint
didn't accept it and there was no picker in the app. Adds coverUrl to
PATCH /restaurants/:id and a cover photo picker in the mobile account
screen, next to the existing logo picker.
