consumables.py 279 -> 217. check_page_delivery and _snapshot_counters
move to _page_delivery.py.
The state-file primitives stay put: test_consumables.py patches
_load_consumable_state, _save_consumable_state and CONSUMABLE_STATE_FILE
on consumables, and moving them would have let a test write to the real
~/.config/brother_printer/state.json. Verified by mtime after the run,
not just by a green suite.
test_consumables_part2.py patches the same three primitives from both
sides of the seam, so it gains a second MOD_PD applied per class rather
than a blanket swap. Pass count is 402 before and after.
