Runs the full m0NN migration chain against a fresh temp SQLite via the
lnbits Database, then round-trips a room + booking through crud (exercising
the m002 checkin_instructions column, big_int amounts, and is_available on
real rows). Closes the gap that let the #13 SQLite-index bug ship: the rest
of the suite monkeypatches crud, so migrations were never executed.
Isolation is import-order-independent: monkeypatch settings.lnbits_data_folder
to tmp_path, build a fresh ext_chatelet Database, swap it into crud for the
test. Verified it fails (sqlite3 OperationalError) if the #13 bad-index syntax
is reintroduced.
