Fix integration: CORS, auto-start, mount names, Icecast bypass

CORS fix (icy-protocol.lisp):
- Add Access-Control-Allow-Origin: * to stream response headers
- Browser audio player can now connect cross-origin (port 8080 -> 8000)

Auto-start (asteroid.lisp -main):
- Start cl-streamer pipeline automatically on boot
- Load stream-queue.m3u and begin playback immediately
- Wrapped in handler-case so streaming failure doesn't block web server

Mount names (stream-harmony.lisp):
- Renamed /stream.mp3 -> /asteroid.mp3, /stream.aac -> /asteroid.aac
- Matches existing frontend URLs, zero template changes needed

Icecast bypass (asteroid.lisp, listener-stats.lisp):
- Front page uses get-now-playing-stats instead of icecast-now-playing
- check-icecast-status returns cl-streamer status when pipeline is active
- check-liquidsoap-status returns N/A when using cl-streamer
- asteroid/icecast-status API returns cl-streamer data directly
- poll-and-store-stats uses cl-streamer listener counts directly
- Eliminates hanging HTTP requests to port 8000 for Icecast XML

Tested: full browser streaming working end-to-end
