Add Customer Health decision card to tenant & workspace detail pages (spec 245).
What I changed:
- Render a decision-first Customer Health card on tenant and workspace detail pages.
- Reuse `WorkspaceHealthSummaryQuery` and preserve `window` query param.
- Update attention widget link text to "Review health details" and include `?window=`.
- Add/adjust tests to cover new behavior and explainability.
- Run Pint formatting.
