test: fix BackupSet empty state create assertions

Implements Spec 092 legacy purge.

Key changes:
- Remove legacy Inventory landing page + view; link Inventory entry directly to Inventory Items.
- Update Drift landing copy to "operation runs"; remove URL heuristic from context bar.
- Remove legacy redirect shim route and assert 404 for old bookmarks.
- Staged job payload change: remove legacy ctor arg; keep legacy field for deserialization compatibility; new payload omits field.
- Remove legacy notification artifact.
- Remove legacy test shim + update tests; strengthen guard suite with scoped exception for job compat field.
- Add spec/plan/tasks/checklist artifacts under specs/092-legacy-purge-final.

Tests:
- Focused Pest suite for guards, legacy routes, redirect behavior, job compatibility, drift copy.
- Pint run: `vendor/bin/sail bin pint --dirty`.

Notes:
- Deploy B final removal of `backupScheduleRunId` should occur only after the compatibility window defined in the spec.
