feat(android): Settings — My Requests + Admin tiles

Audit v2 reachability gap: Requests screen was orphaned (no entry
point) and admins had no Settings-side affordance for admin tools.
Both now surface as ListTile-style cards in the Settings stack with
Lucide chevron + leading icon, matching Flutter's layout. Admin tile
gated on SettingsState.isAdmin (sourced from AuthController.
currentUser, plumbed through the combine() chain).
