Subject: Zap receipts read as zaps. A receipt (9735, or coinos's 9737) reached
 as a note — someone reacted to a zap, and the reaction was followed — showed
 as "a kind 9735 event this app doesn't show" under the LNURL server's name.
 It now shows the zapper's face and name, "⚡ zapped 21 sats" and what they
 said with it. tools/zap-receipt-row-test.js
