Summary
Alerting v2 adds a query preview tab to the rule attachment sidebar (rule details flyout), surfacing the QuerySandbox component so users can inspect a rule's underlying ES|QL query without leaving the sidebar context. This is a UI improvement that improves discoverability and debugging of rule queries. Documentation covering the rule sidebar should mention the new query preview tab and its scope (currently restricted to Agent Builder rules). Stack only, from 9.5.0 (technical preview).
Why this needs docs: A new UI tab in the rule sidebar is user-visible and should be captured as part of the Alerting v2 UI overview, but it rolls up into the broader rule details page documentation rather than needing a standalone doc issue.

- What the docs say: No Alerting v2 UI docs exist yet.
- What to add: When documenting the Alerting v2 rule details page, include the rule attachment sidebar and its tabs: Overview, Execution History, and Query Preview. Note that the Query Preview tab is only shown for Agent Builder rule types and renders the ES|QL QuerySandbox. This item rolls up into a broader Alerting v2 UI how-to page. Stack only, from 9.5.0 (technical preview).
