It has nothing to do with the ethanol, the uncured resin simply covers the surface and fills small holes, hiding them
I would guess it’s something funny with the 3d model, air bubbles in the tank wouldn’t be consistent between layers. Try inspecting the problematic layers on your slicer.
Almost looks like the slicer might be trying to add FDM style infill, make sure it is not.
Well first off, how nice/tolerant is your management? Do you have savings? Some companies can fire people over this stuff, other will just ignore it.
The easiest (and least likely to make anyone mad) solution would just be to bring in your own machine and use celular internet. This way your setup will be completly seperate from the company network, and they can hardly claim you were exposing them to malware or anything. On the other hand you might have problems accessing devices like printers without copying files back and forth (are USB drives allowed?).
