'Add Service' only worked for the 19 apps in the hardcoded
known_service_port map — everything else failed with 'Unknown app'.
tor.create-service and tor.toggle-app now fall back to the app's live
launch address from the scanner state, so any manifest-driven app gets
a .onion without a per-app entry (the static map still wins for
protocol services like bitcoin, which must expose 8333, not a UI port).
toggle-app also no longer writes a broken port-0 HiddenServicePort for
unknown apps.
Every successful package.install now auto-creates the app's hidden
service (detached, best-effort, retries while the scanner derives the
port; skips protocol services and existing entries).
The demo mock gains stateful tor.create-service/tor.delete-service so
the demo round-trips instead of erroring.
