GE-Enforce: prefer DNC reg MachineNo over machine-number.txt

Browse Source 
machine-number.txt holds the imaging-time MN. PCs imaged with
placeholder 9999 (tech intends to flip via Set-MachineNumber later)
keep 9999 in that file even after Update-MachineNumber writes the
real MN to HKLM:\...\Dnc\General\MachineNo. Status.json was reporting
9999 across the fleet because of this.

Now reads DNC reg first; only falls back to machine-number.txt if reg
is missing or also 9999. Existing convergence-check.txt unchanged.
