fix(web-api): fix flaky timeout test by mocking network request

zimeg · Claude · zimeg · commit a4ab70aab237 · 2026-02-10T10:34:35.000-08:00
The timeout test was making real network requests to slack.com, causing
intermittent failures due to SSL connection destruction race conditions
(ECANCELED errors). Now uses nock to mock the network with delayConnection.
