/**
 * @fileoverview chainweb_poll - poll /poll endpoint for tx results.
 *
 * Uses /poll (NOT /listen) because nginx on devnet enforces a hard 60s
 * upstream timeout, and /listen holds the connection open (504 bug in user
 * memory). /poll is an idempotent "give me anything you have right now"
 * request we call repeatedly until the result appears or timeout.
