Place the Wipe Tower in the Profile Validator

Browse Source 
The validator forces a two-filament print with the prime tower on and
slices it at the config default position (x 15, y 220), which lies off
any bed shallower than the tower. It calls validate() but slices
regardless, so the off-plate tower was exported silently; with the
generation-time footprint check it is rejected instead, and 522 of the
1013 printer presets failed the slice check.

The validator now positions the tower the way the GUI and CLI do before
slicing: beside the centred cube, clear of the edge exclusion strips some
beds carry, then pulled inside the printable outline by the tower's own
estimated footprint.
