Stop leaking demo flag into the shipping codebase

Removes the orange "Demo menu" banner from the public menu and the
"Demo mode / Reset now" header from the admin SPA. Drops `demoMode`
from the catalog and `/me` API responses, the shared schemas, and the
frontend store/types. Rewrites two demo-flavored chat strings to
locale-neutral wording. Demo deployment still works via DEMO_MODE on
the backend; it just no longer contaminates what self-hosted
restaurants ship.
