Adds Player.is_admin (creator starts with it; backfilled by migration).
Admin-key-authenticated POST /admin/set-admin grants/revokes it from the
admin panel; the creator's privileges can't be revoked. Admin-gated
backend routes (dev mode, skip character creation) and frontend controls
(corner menu, lobby start, scene start, end story) now check is_admin
instead of is_creator, and admins get the admin_key in their state blob
so granted players can open the admin panel.
