Update design for LRS-150-24 UPS supplied by LDO kits

[eduncan911]

The Meanwell 150W PSU that is supplied in the LDO V0.1 (and V0.2 I think?) kits is larger than the CAD's version of the 100W.

Hole to screw down the PSU doesn't align with the deeper 150W variant (look for the hole in the baseplate).

There's also no room for the buck converter here either.
