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-writer run: Compliance screen page re-verified on prod (Deficiencies shot retaken). Reference: Pagination now names the 24h Sessions window and Errors names the 429 Retry-After. Guides and Changelog not due. Full gate green; PR #4586 merged.
