Drives RLS directly as the non-superuser app role: deny-all with no scope,
own-rows-only scoped reads, zero-row cross-user UPDATE/DELETE, rejected
cross-user INSERT, FORCE + NOT NULL user_id, cascade on DeleteUser. Also pins
the EXACT set of public tables with row security off, so a new table added
without RLS fails CI rather than passing it (ADR-033). The existing test only
named transcripts; #33's "the only non-RLS table" is false -- invitations,
user_identities and schema_migrations are off too.
Red: relation "uploaded_transcripts" does not exist. Set test passes today
and guards the migration that follows.
