delete_clear_tokens_sjt() relied on cascade to remove the associated schedule when deleting the cleanup_tokens SystemJobTemplate. In migration context with polymorphic models, the cascade did not reliably fire, leaving an orphaned schedule whose unified_job_template referenced a missing row. Explicitly delete associated schedules and clear stale next_schedule references before deleting the SJT. Add defensive handling in ScheduleSerializer.get_related() and get_summary_fields() so orphaned schedules degrade gracefully instead of raising RelatedObjectDoesNotExist. Fix the existing test assertion that used a JOIN-based query incapable of detecting orphans, and add coverage for next_schedule reference cleanup. Fixes: AAP-92564
Databases that already ran migration 0204 may have orphaned "Cleanup Expired OAuth 2 Tokens" schedules left behind by the broken cascade. Remove them and clear any stale UnifiedJobTemplate.next_schedule references. Add a test that simulates the orphan scenario by deleting the UJT via raw SQL and verifying the migration repairs it.

In `@awx/main/tests/functional/migrations/test_token_sjt_removal.py`:
- Line 72: Add a separate surviving UnifiedJobTemplate in both tests that points
next_schedule to sched, rather than assigning the reference to the token
template being removed; after each cleanup path, assert that the surviving
template’s next_schedule is cleared while preserving the existing deletion
assertions.

Apply the gateway backport migration pattern (AAP-87599): re-parent 0212_cleanup_orphaned_token_schedules to depend on 0207_merge (the common ancestor with tower/stable-2.7) instead of 0211. Add 0213_merge_0211_0212 to converge the parallel paths on devel. This allows the backport to tower/stable-2.7 to use the identical 0212 migration file with no changes.

Use the cleanup_sessions SystemJobTemplate (which survives the deletion) as the next_schedule reference holder, so the assertion actually proves the UPDATE ... SET next_schedule = NULL logic works rather than being masked by the referenced UJT itself being deleted. Ref: AAP-92564 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
