fix: mark admin/platform queries as SVC-005 exceptions

These queries are intentionally not vendor-scoped:
- inventory_service: get_vendors_with_inventory_admin (admin cross-vendor)
- background_tasks_service: get_running_test_runs (platform-level)
- marketplace_product_service: get_inventory_info (admin/internal)
- feature_service: Feature query (platform-level, not vendor-scoped)
