feat(admin-web/auth): support phone-or-email login and dim shell on expiry

Login form takes a phone-or-email identifier; user info now exposes phone
so the shell can fall back through name → phone → email. When membership
expires, the app stays on the current route but renders a minimal blocked
state in the shell instead of redirecting to a dedicated page; an Axios
interceptor flips the local session into the blocked state when the API
returns trial/subscription errors.
