List Miro invoices

List Miro company billing invoices. Returns total plus invoices (id, date, description, amount, status, pdfUrl) — metadata only, with dates as ISO YYYY-MM-DD and amounts with their ISO currency, e.g. "10.00 EUR". Feed a row's pdfUrl to miro.com/download_invoice to fetch that invoice's PDF. Only a company or team billing admin can see billing; a personal account with no organization is reported as such rather than timing out.
