Description, as the server wrote it: ```untrusted-server-text WRITE: adds a new client to the SuperFaktura address book (only the name is required). Nothing is sent to the client.

A final regular invoice cannot be created here. It is NOT sent (no e-mail, no post), NOT marked paid or sent, and has no payment link or discount. Give an existing client_id (its name is read first with one extra GET /clients/view/{id}, so the call uses 2 requests of the daily quota) OR a new client's name (+ optional ico/dic/ic_dph/address...). Items: name, unit price without VAT, VAT rate, quantity. Not idempotent: pass a checksum (max 32 chars) so a timed-out call can be recovered with superfaktura_get_response_by_checksum instead of retried.
