Extend the admin allow-list so upcoming admin screens can reach quiz
content and activity, sent dares, and dare chat messages. Also fix a
schema drift where question_packs.scheduled_release_at and
release_notified existed in the database but were missing from the
drizzle TS schema, which could have let a future generate propose
dropping them.
Note: no profile_settings table exists in the schema. The
profile-settings domain reads and writes the existing profiles and
notification_preferences tables, so that entry was intentionally
omitted pending a product decision on which table it should map to.
