Howard Enos 98f875131e fix: use WindowStyle=Hidden instead of NoNewWindow in headless scanner dispatch ...

NoNewWindow caused scanner processes to inherit PowerShell's stdout/stderr
pipe handles from the GuruRMM agent. If any scanner hung in Session 0
(e.g. AdwCleaner GUI init), it held the pipe open after PowerShell exited,
blocking the GuruRMM command for hours until the server-side reaper fired.

WindowStyle=Hidden gives each scanner its own window/console so pipe
handles are not inherited. Scanner processes that timeout are still killed
by Wait-ProcessWithTimeout; the overall scan completes normally.

Verified: full pipeline completes in ~7.5 min on RMM-TEST-MACHINE with
EICAR detection, GURUSCAN_RESULT_JSON emitted correctly.
