Complete the WebView/server side of native LiveKit calls:
- routes.js: /api/calls/answered (markDmAnswered) + /api/calls/end (endCallByRoom) so
the server learns a NATIVE call was answered/ended (native media runs over LiveKit,
bypassing our mesh/WS lifecycle). Additive no-ops for WebView/mesh calls.
- home.html: for native calls the WebView no longer joins the room (one connection per
identity — the plugin holds it). answerCall -> POST /api/calls/answered + clear invite;
endCall -> /api/calls/end (answered) or /api/calls/decline (still ringing). Outgoing
DM/group calls fetch a LiveKit token and hand it to NativeCall.reportOutgoingCall
instead of enterMeeting. Removed the old callHandoff mic-repush.
Server deploys now; the plugin (native LiveKit) needs a Codemagic build. Still gated by
CALLKIT_ENABLED=0 — flip to 1 only after the build is installed.
