 * Void credit grant
 *
 * Void a credit grant, forfeiting the remaining unused balance.
 *
 * Voiding is a forward-looking, irreversible operation. Credits already consumed
 * by usage remain unaffected — only the remaining balance is forfeited. The grant
 * reads as `voided` status afterwards. Payment state is not adjusted when
 * `payment_adjustment` is `none`, so invoice-backed or externally collected
 * payments may still collect the original amount. Only `active` grants can be
 * voided; voiding a pending, expired, or fully consumed grant returns a conflict.
 * Retrying a successful void is an idempotent success.
