fix(lora): record how the pass left the weights

The mode shown in the load and unload lines was derived at print time
from the live fuse setting, so a set applied under one setting was
reported under whatever the setting said later, and the unload line
described the pass that was about to replace it rather than the one
being removed. The pass records the mode it actually used.

last_backup_size was created on lora_common by assignment from
networks.py and read back through a getattr default; both fields are
declared where they live now.
