fix(#71,#73): remove class-level permission gate and add annotationId to notifications

- Remove @RequirePermission(READ_ALL) from NotificationController class level so
  authenticated users with any permission (or none) can access their own notifications
- Add V19 migration, annotationId field to Notification entity and NotificationDTO
- NotificationService now stores annotationId from comment on both REPLY and MENTION
- Update controller tests: permission tests now expect 200, DTO constructor includes annotationId
