-- BIGSERIAL on each investigation table created auto-sequences (e.g.
-- `evidence_evidence_pk_seq`) that 0004 forgot to GRANT to the investigator
-- role. Without those grants, every INSERT failed with:
--   permission denied for sequence evidence_evidence_pk_seq
--
-- Idempotent. Apply as supabase_admin.
