Finance

Get the next available invoice number for the authenticated company.

Returns the next available invoice number for the company resolved from the bearer JWT. The caller must hold the <code>FINANCE</code> permission on the target company. <strong>This operation is NOT idempotent</strong> — each successful call advances the persisted next-invoice-number counter on luzfin_finance, so the returned value is reserved and will not be returned again. Do not retry on success.
