Vehicles expose their contents, but mechs do not

lowvis is acting wonky with vehicles... turn 1, i can see the contents of vehicles...but not their loadouts. but can't see contents of a mech.

Start by reproducing the LowVisibility behavior described for vehicles and mechs on turn 1, checking both visible contents and loadouts. No files or tests are named, so trace the relevant vehicle and mech visibility handling; done means their contents and loadouts are exposed consistently.
