Update documentation for console feature and API reference

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 PR #7648 (Your organization re-verified on prod, Terminal WebSocket checked) rebased on develop and re-queued; lane failure not attributable to the docs-only diff — docs suites and quick gate green. Memory: none applied.
