P2 Badge Assert the NULL-generation guard for every artifact table

The test claims to guard all artifact deletes, but after document_images these assertions only prove that a same-table replacement subquery exists somewhere in the SQL. A schema regression that changes, for example, document_memory_cards back to an unconditional nullif(metadata->>'index_generation_id', '') is null delete would still pass as long as the from public.document_memory_cards replacement text remains, so the destructive drift this test is meant to catch can slip through. Please assert the full is null and exists (...) guard per table, or isolate each delete block before checking it.
