Settings: premium-gated notifications UI and layout fix

Show the reminders block only for premium users via a notifications
stack whose visibility tracks entitlements. Rebuild the embedded
settings view when premium status changes so the page stays in sync.
Fix Auto Layout by adding the notifications stack to the parent before
pinning its width to the outer stack (avoids missing common ancestor).
