  Handle IRN cancellation with 24h window + Credit Note fallback
  
  cancelInvoiceGst(invoiceNumber, reason, creditNoteNumber):
  - Within 24h: cancel IRN directly (EWB auto-cancelled by NIC)
  - Past 24h: generate Credit Note e-invoice (DocType=CRN) referencing original invoice
  - DC invoices: cancel standalone EWB regardless of time
  
  generateCreditNoteIrn(originalInvoice, creditNoteNo, reason):
  - Same endpoint as IRN generation but DocType=CRN
  - RefDtls.PrecDocDtls references original invoice number and date
  - No EWB details in credit note
  - IRN persisted in einvoice_details table
  
  Sandbox verified: CRN generation works with DocType=CRN
