List numerical seriesReturns the numerical series used for creating public documents. The endpoint does not paginate; it returns the full relevant dataset for the supported document type provided in the required `documentType` query parameter. Supported values are `invoice`, `proforma`, `credit-note`, `order`, and `quotation`. In addition to the internal counter `nextNumber`, the response also includes `nextDocumentNumber` and `nextVariableSymbol`, so an integrator can see in advance which document number and variable symbol would be generated from a given series.
