Documentation writing for Jaah console application

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: Audit page refreshed on prod with admin captures, terminal WebSocket refusal body/429 fixed, Changelog 2026-10-22 → v1.2.3764 (+1 bullet). Guides nothing due. Quick gate green; PR #6692 queued to merge lane. Memory: used mem-22234, mem-15203; proposed none.
