So as far as lifting up one end and dragging the other on a four-wheel drive vehicle, I myself would not allow that

I definitely wouldn't do one end, but all 4 lifted would be fine. I wouldn't be concerned with a tow truck lifting one axles and the other axle on wheel lifts to get it out of a garage personally. You just don't want it putting stress on the driveline.

It's under warranty, I'll be @$#$% if I'm going to pay for (and install) a battery they owe me.

The biggest issue here is that I don't want another oem battery and they certainly aren't going to replace it with one I do want in their dime.

But it should be fine to use wheel lifts to get it out of the garage and then put it on a flatbed?

Yes, this is fine

I don't have the manual handy - but if that 12v battery is still in the mix, won't it kill down any battery that you try to connect to release the parking brake - unless there's some special connection that avoids being in parallel with a dead and parasitic battery?

Here's what the manual has to say

Maybe there's a fuse I can pull to release the parking brake?

There's a procedure in the manual that actually calls for hooking up a battery temporarily to actuate the parking brake.

Likely the battery is dead. Worth remembering that what you're trying to do is charge up the 12v so the voltage is high enough to close the hv battery contacts, not push enough amps to turn a starting motor. If the 12v is dead, it'll pull down the voltage of whatever you're trying to charge up with and never really get there.
