feat: enhance project and scenario detail pages with metrics, improved layouts, and updated styles

changelog.md

@@ -12,3 +12,4 @@
 - Added scenario comparison validator, FastAPI comparison endpoint, and comprehensive unit tests to enforce FR-009 validation rules through API errors.
 - Delivered a new dashboard experience with `templates/dashboard.html`, dedicated styling, and a FastAPI route supplying real project/scenario metrics via repository helpers.
 - Extended repositories with count/recency utilities and added pytest coverage, including a dashboard rendering smoke test validating empty-state messaging.
+- Brought project and scenario detail pages plus their forms in line with the dashboard visuals, adding metric cards, layout grids, and refreshed CTA styles.
