Jaah Docs Writer Due Items PR

Docs-writer run. Follow apps/docs/WRITER.md on develop. Do each item that is due, all in ONE PR: 1. Screens: one console feature's reference page. 2. Guides: one Get started, Using Jaah or FAQ item. 3. Changelog: the next batch of prod promotions 4. Reference: the Jaah API and Real-time reference against the code. Sign in only through the capture helper. Nothing due: end with no PR.

Docs run merged in #4677: Schedule + Persona details refreshed with new prod captures, changelog for v1.1.7803. Guides and Reference had nothing due. CI gate green. Local full gate: 5 API failures already on develop, not from this diff.
