feat(auth): wire getAdminUser() to Auth.js v5 Google sign-in
After a user signs in with Google, they land on /admin but see
'Your account does not have admin access' because getAdminUser()
only checked the legacy dev_session and rc_auth_uid cookies.

This completes the Auth.js path:

- New src/lib/db.ts: shared pg.Pool singleton (extracted from
  src/lib/auth.ts). The single connection pool for the whole app
  — server actions, API routes, and Auth.js all import from here.

- src/lib/auth.ts: imports the shared pool, signIn event now calls
  the new upsert_admin_user_for_authjs RPC (idempotent) to
  auto-create a platform_admin row on first sign-in.

- New supabase/migrations/209_authjs_auto_create_admin.sql:
  - Defensive ALTER TABLE ADD COLUMN IF NOT EXISTS for
    can_manage_settings (was likely dashboard-added, not in any
    tracked migration)
  - SECURITY DEFINER RPC upsert_admin_user_for_authjs(p_user_id UUID)
    that inserts a platform_admin row with all permissions true
    and ON CONFLICT (user_id) DO NOTHING
  - NOTIFY pgrst to reload PostgREST schema cache

- src/lib/admin-permissions.ts: new Auth.js session check between
  dev_session and rc_auth_uid. Uses auth() from @/lib/auth to
  decrypt the JWT cookie server-side, then getAdminUserFromPool()
  queries admin_users + admin_user_brands via the shared pool.
  Legacy rc_auth_uid path unchanged (deferred).

- src/middleware.ts: recognizes Auth.js session cookies
  (authjs.session-token and __Secure-authjs.session-token) at the
  edge so signed-in users aren't bounced to /login.

Flow after this change:
  Dev/demo:  visit /admin → middleware auto-issues dev_session → in
  Prod:      click Google → Auth.js OAuth → signIn event creates
             admin_users row → redirect to /admin → getAdminUser()
             reads JWT, queries pool, returns platform_admin.

-- 209_authjs_auto_create_admin.sql
-- Auto-create a platform_admin row when a new user signs in via Auth.js.
--
-- Called from the `signIn` event in `src/lib/auth.ts`. The RPC is
-- idempotent (ON CONFLICT DO NOTHING) so repeat sign-ins are no-ops.
-- Defensive: ensure can_manage_settings column exists. It was likely
-- added via the Supabase dashboard (it's referenced in the TypeScript
-- `AdminUser` type at `src/lib/admin-permissions-types.ts` but not in
-- any tracked migration). ADD COLUMN IF NOT EXISTS is safe to re-run.
ALTER TABLE admin_users
ADD COLUMN IF NOT EXISTS can_manage_settings BOOLEAN NOT NULL DEFAULT false;
-- SECURITY DEFINER RPC: upsert a platform_admin row for the given
-- Auth.js user id.
--
-- Bypasses RLS on admin_users (which is enabled — see
-- 109_enable_rls_critical.sql:21). Runs with the function owner's
-- privileges so the auto-create on first sign-in can always succeed.
