startnet: map the per-PCTYPE media view for shopfloor builds

Browse Source 
Maps Z: to _media\<PCTYPE> instead of the shared gea-shopfloor media, so
PESetup's unfiltered CopyPackages stages only this type's payload rather than
every shopfloor payload on every bay.

The mapping is validated rather than assumed: it probes
Z:\Deploy\Control\HardwareDriver.json, which resolves only when the view exists
AND its symlinks are intact, so a dangling view cannot image silently off a
half-mapped drive. On any failure it falls back to the shared media with a
console warning - the bay still images, it just stages the union, which is
exactly today's behaviour. That fallback also covers the second WJ PXE box,
which has no _media views yet.

Z: is freed before the mapping. A leftover mapping makes net use fail with
"device already in use", and the probe would then pass against the OLD media -
a silent wrong-payload build, which is the failure this change exists to
prevent.

Views are built by scripts/build-pctype-media.py.

REM concurrently and CopyPackages is fail-fast, so changing a path mid-copy
REM would fail some OTHER bay's imaging.
