humility auxflash lets you erase but not write an active slot

for some reason, auxflash lets you erase an active slot but when you try to write something to it, Hubris throws an error. It seems like one of these two things is incorrect as I would assume that an active slot can either not be touched at all or you should be able to do anything to it.

Start by reproducing the reported auxflash erase and auxflash write --slot 2 commands, then trace how active slots are handled for each operation and where the SlotActive error is returned. Done means active-slot behavior is made consistent: either both operations are rejected or both are supported, with the status output and command behavior agreeing.
