Export-FormtracepakInventory: drop Get-Service entirely (SCM hang)

WJF00052 / WJF00083 / WJF00084 / WJF00159 hung indefinitely on step [5/5]
during the 2026-05-24 capture pass and the operator killed the .bat,
leaving empty inventory CSVs. The earlier Start-Job + Wait-Job -Timeout 30
guard (commit fce6680) was insufficient: Stop-Job on a Get-Service that's
blocked on a degraded Service Control Manager can itself block in the SCM
call (Sentinel HASP driver service in particular has been observed to
wedge Get-Service for minutes), so the main script never unblocked even
after the 30s timeout fired.

Service state isn't load-bearing for identifying the install on a bay
(version + model + DeviceName come from disk + registry, not the SCM),
so the cleanest fix is to drop the Get-Service block entirely. Get-Process
is fast and stays. Step [5/5] label changed from "Checking running
processes and services" to "Checking running processes".

Smoke tested on win11 VM: full Export against a real v6.213 / AVANT
install completes in ~25 s (was 2.9 s with no install, 25 s now reflects
the legitimate ~95k registry walk that dominates the runtime - not the
service hang).
