An open guest WebSocket stamped isGuest/botScope once at upgrade and
never rechecked them, so it kept streaming bot state after an admin
disabled guest mode or narrowed guestMode.bots. setupWebSocket now
returns { cleanup, refreshGuestPolicy }; POST /api/bot/settings invokes
refreshGuestPolicy after saving a guestMode change, force-closing guest
sockets when disabled and live re-scoping them otherwise.

Adds an admin/member role to WebUI auth. /api/users and /api/audit
are now gated by a requireAdmin middleware; all other authenticated
endpoints accept both roles. Schema migration defaults all existing
users to admin to preserve access. POST /api/users defaults new users
to member; first-run setup always creates an admin. Adds PATCH
/api/users/:id/role with last-admin demotion and deletion guards.
