Returns a paginated list of recurring-billing cycles for the authenticated
company. Results are ordered by created_at (newest first).

A cycle owns the cadence, amount and next billing date behind a service plan's
recurring charge — the service plan's own fields do not. Follow
billing_cycle_ids from a service plan or a serviced job to get here.

Cancelled and rollup cycles are included. Filter them out with status and
pricing_mode if you do not want them; they are returned by default so that a
sync does not read an omitted row as a deletion.

next_amount is in dollars, and is null for rollup cycles, which charge
whatever work is outstanding when the period closes.

Requires the service_plans:read scope.
