Mercury CLI has no reimbursements resource

Mercury's CLI exposes accounts, recipients, payments, transactions, treasury, etc. but there is no dedicated reimbursements subcommand. The canonical flow is two steps: (1) mercury recipients create with --electronic-routing-info as JSON containing accountNumber/routingNumber/electronicAccountType (e.g. personalChecking), then (2) mercury payments create --payment-method ach --recipient-id ... --account-id ... --amount ... --idempotency-key $(uuidgen). Receipts attach afterward via mercury transactions attachments.
