Documentation writer run for multiple sections

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.

Playbooks reference re-shot on prod (6 shots) and re-verified. Guides, Changelog and Reference were not due; the API pages match the code. Quick gate green; PR #6953 is queued in the merge lane. Visual check done: clean. Memory: used mem-22234.
