Add Apple container deployment for daemon + dashboard

install-apple-container.sh builds and (re)starts both containers
(dashboard mounts reports/ read-only, port 8090); --boot installs a
LaunchAgent since Apple container has no restart policy. README covers
the new deploy path, SearXNG settings, and the dashboard.
