/**
 * End the modules whose cancellation date has arrived.
 *
 * A module is cancelled monthly and the cancellation lands at the end of the
 * term the customer has already paid for — the same rule a package downgrade
 * follows, and for the same reason: what has been paid for is kept. So
 * BookAddon::cancelAtPeriodEnd() writes an appointment on the booking and leaves
 * the module running. This keeps it.
 *
 * Stripe has already been told at the moment of cancellation; there is no item
 * left to remove here. What ends now is the module itself — the entitlement, and
 * for a storage pack the space on the machine — and the entry in the proof
 * register that says the customer stopped paying for it.
 *
 * Safe to run as often as the scheduler likes: BookAddon::cancel() claims the
 * cancellation conditionally, so a second tick over a module that has already
 * ended writes nothing and records nothing.
