let's say my onboard battery is stone dead (which I expect they are),
but I want to reset my camera back to its original factory defaults,
following the recommended procedure. if I follow the recommended
procedure while never UNplugging the camera from its "wall wart" power
supply, shouldn't the camera "return to" it's original default IP
address and hold that default IP address *ASSUMING* I've never unplugged
the wall power supply adapter from the camera?

After reset the camera software might perform a reboot and load back
the settings from the NV memory which is powered by the batteries.
It's only powered from battery when there's no external power.

It's entirely possible that the battery is only used to hold a time/date
value and that the configuration is held in EEPROM which doesn't rely on
a battery to keep its contents. Finding out how to perform a factory
reset would be useful in this case.

Once the OP has done that, as another poster suggested, use a crossover
cable to connect it directly to a PC, setting the PC's IP address/subnet
mask to be in the same subnet as the factory default for the camera. If
that fails then contact Axis Tech support.
