fix: address code review feedback

- SettingsView: replace broken Toggle+constant with a Button that directly
  opens system notification settings (Toggle was bound to .constant(true)
  and onChange never fired)
- HTTPClient: append query parameters to URL for GET requests instead of
  putting them in the request body (body is ignored for GET)
- PushNotificationService: document why info-severity alerts skip Live Activities
- NotificationsViewModel: document polling page-reset behavior
