chore: remove leftovers of the deleted onboarding AI offer and badge

The end-to-end setup still seeded the shared-provider offer's account
and captured its session, although the journey that used it is gone.
Three comments still pointed at what was removed: the tour launcher
cited the deleted personal-record badge as its model, the personal
record worker said the badge still renders, and the morning briefing
push said a concerning reading goes out as an anomaly notification,
which nothing sends.
