Let a printer driver carry the name Windows actually matches on

Browse Source 
The driver form and the API both dropped `drivername` and `vendorid`. POST
returned 201 with both null, PUT accepted them and stored nothing, and no
screen offered either field - so there was no interface in the product that
could set them.

That is not a cosmetic gap. `drivername` is the exact string the INF declares,
and Add-PrinterDriver matches on it; `name` is ours to choose and means nothing
to Windows. With it null the shipped converger has nothing to match and
installs nothing, and the drift check that compares an observed driver name
against the expected one could never fire, because the expected value was never
stored. `vendorid` is how a universal driver (HP UPD, Xerox GPD) attaches to a
whole make instead of needing a near-duplicate row per model.

Both are now read on create and update, and the driver form gained the two
fields with hints saying what they are for - the INF name box says plainly that
leaving it blank means the converger cannot install that driver. A whitespace
value clears rather than stores: an empty box means "not known", and a blank
string would look set and match nothing.

Three tests. Verified by planting: drop the two fields from the create path
again and the round-trip test fails.
