feat: add dedicated TopUpResult page for payment return flow

Replace toast-based payment return with animated result page showing
pending/success/failed/timeout states. Extract shared Spinner,
AnimatedCheckmark and AnimatedCrossmark components. Add sessionStorage
persistence with validation and TTL for cross-redirect payment data.
Unify ProtectedRoute with withLayout prop, add aria-live accessibility.
