fix(run-ops split): scalar-only bulk-action queries after group relation drop

The activation schema removed the BulkActionGroup.items and BulkActionItem.group
Prisma relations, but PerformBulkActionService still queried them via include,
which would fail once the client regenerates. Switch to scalar groupId lookups and
read the action kind from BulkActionItem.type. Also drop a stale test comment.
