-- Migration: stream transactions changes via Supabase realtime
--
-- The dashboard sidebar transaction badge now listens to postgres_changes
-- on public.transactions. Adding the table to supabase_realtime lets the
-- browser receive INSERT/UPDATE/DELETE events and keep the uncategorized
-- count in sync without a manual refresh.
--
-- RLS already scopes transactions to the active company, so realtime only
-- delivers rows the current user is allowed to read.
--
-- Idempotent so preview branches or partial re-applies do not fail if the
-- publication already includes the table.
