Rudder with RUDDER_ENGINE=0 never starts the engine, and a page on another machine never offers to record the server's mic

Browse source 
A server where Rudder is laptop-only (RUDDER_ENGINE=0) no longer starts a
leftover engine binary. If an engine that records its own machine's microphone
is reached from another machine anyway, Rudder shows the laptop notice and
disables Record instead of recording the server.
