Rename public discovery app from "finder" to "koja"

Rebrand the public café-discovery app: directories web/finder→web/koja and
docker/finder→docker/koja, plus all service wiring (docker-compose, Caddy
subdomain koja.meezi.ir, env vars KOJA_PORT / NEXT_PUBLIC_KOJA_URL, CI
workflows) and the app's display name (Koja / کجا).
