# Record a payment (règlement) on a validated invoice in the SANDBOX.
#
# Input: a JSON object on stdin (or a file path in $1):
#   invoice_id   (required) the invoice to pay
#   kind         "customer" | "supplier"      (default "customer")
#   mode         "VIR" | "CB" | "CHQ" | "LIQ" (default "VIR")
#   account_id   (required) the bank account id receiving/paying
#   date         "YYYY-MM-DD"                  (default today)
#   amount       (REQUIRED for supplier; customer pays the full remaining)
#   transaction_id (recommended) the originating bank transaction id (the Qonto/Wise
#                tx id from the feed). Stored on the payment's bank line
#                (llx_bank.num_chq) so the règlement reconciles to the feed by id.
#                `num` is a back-compat alias for the same field.
#                NORMALIZED before POST: Dolibarr stores num_payment in varchar(50)
#                (llx_paiement.num_paiement / llx_paiementfourn.num_paiement) while
#                Qonto ids run ~67 chars (<org>-<n>-<n>-transaction-<uuid>), so
#                everything through "transaction-" is stripped and the UUID suffix
#                (globally unique, ~37 chars) is the canonical stored form. Wise ids
#                (short numerics) pass through unchanged. An id still >50 chars after
#                normalization is REFUSED with an error — never truncated silently.
#   comment      (optional)
#
# The invoice must be VALIDATED first (invoice-create.sh ... "validate":true).
# Emits {id, bank_transaction_id, transaction_id} on stdout — `transaction_id` is
# the NORMALIZED num actually stored (what bank-match keys on). `bank_transaction_id`
# is the Dolibarr bank line (llx_bank.fk_bank_line) the payment created — the id
# bank reconciliation (arcodange-bank-reco) keys on to link this règlement to a
# statement line. Recording without a transaction_id warns (it won't auto-reconcile).
