enricobuehler 7e31020c1c fix(windows-host): second-host guard — classify ACCESS_DENIED on the instance mutex as in-use
On-glass the SCM service creates Global\punktfunk-vdisplay-manager as
SYSTEM, so a second elevated-admin host's CreateMutexW fails ACCESS_DENIED
(the implicit open is checked against the SYSTEM DACL) before the
ALREADY_EXISTS branch can fire — right refusal, wrong message. Map it to
the same loud "another instance is live" error.
