fix(auth): port dev auto-login to Next.js 16 proxy.ts
Next.js 16 renamed middleware.ts to proxy.ts and only allows one of the
two. Delete src/middleware.ts and rewrite src/proxy.ts to do the dev
auto-login + /login bounce + /admin gate explicitly (no NextAuth auth()
wrapper — auth.handler() returns a NextMiddleware taking (req, event),
which makes wrapping it awkward when we also need to set cookies on the
response).

Drop the now-dead 'authorized' callback from auth.config.ts (it was only
fired by the NextAuth wrapper, which we no longer use).

Migration 209: add a defensive unique constraint on admin_users.user_id
so the ON CONFLICT (user_id) clause in the new RPC resolves regardless
of whether the Supabase-dashboard-created table shipped with one.

-- 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;
-- Defensive: ensure admin_users.user_id has a unique constraint so the
-- `ON CONFLICT (user_id)` below resolves. The table was created via the
-- Supabase dashboard — we can't be sure the dashboard created a UNIQUE
-- index on user_id. If the constraint is missing, the ON CONFLICT
-- clause will fail the whole "Apply migrations" step on the deploy
-- runner. Skip silently if a matching unique/primary constraint already
-- exists, otherwise add one (cleaning up any duplicate rows first so
-- the ADD CONSTRAINT doesn't fail).
