Upload support attachment

Upload one support attachment using multipart/form-data. Send file as the binary part. Include ticketId only when pinning the upload to an existing ticket; use the public tkt_... value from GET /api/v2/support/tickets or GET /api/v2/support/tickets/{id}. The returned attachmentId is a temporary satt_... upload ID, not the finalized tatt_... ticket-attachment ID that appears on ticket detail responses after a message is stored.
