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 - each item should be a one statement, one short line, not a paragraph with explanations. If it is a minute chore - exclude it . Review several previous batches and fix them 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: refreshed Billing + Jaah AI pages from prod; v1.1.8360/8362 earned no bullets; Sept/early-Oct changelog cut to one-line bullets; reference current. Guides not due. Full gate green, PR #4834 merged, Jaah Deploy success.
