Adds DIRECT value to chk_supplier_projects_platform and chk_psl_platform
constraints. DIRECT represents supplier projects without B[123]_ prefix
(e.g. client.carmoney.ru, cashmotor.ru, numeric phone IDs) — currently
~67 leads/day lost to 302 redirects from webhook validation regex.
Schema-only change; no code yet uses DIRECT — code changes follow in
subsequent commits. Migration is forward-compatible: old code continues
to work with B1/B2/B3 rows.
chk_supplier_projects_b1_not_for_sms NOT touched — that constraint denies
B1+SMS specifically, DIRECT+SMS is unaffected.
