feat(warehouses): gate double-handling fee on a per-booking Yes/No

Double handling billed every import with a matching rule. Add
bookings.double_handling (+ set_at/by), charge only when Yes, expose a
PATCH endpoint (import-only, locked after invoicing, audited) and Yes/No
items in the inventory row menu.
