Each device row now serves one endpoint at a time, picked from a list of
pipe:vrio / pipe:vplasma (first, default) plus the machine's COM ports —
nothing opens automatically at startup. The pipe services gained an
IsListening property and are started/stopped by the row's Open/Close
button instead of running for the whole app lifetime, which also retires
the dual-transport warning. Status line shows the active endpoint;
OFFLINE when none. Standalone vPLASMA is unchanged (hardwired COM12 +
permanent pipe). Also fixes the xUnit1031 warnings in the plasma pipe
tests.
