Dashboard layout overhaul + fix Tremor chart colors and tooltips

- Restructure dashboard: score distribution + recently reviewed stacked in left column,
  full-width map at bottom, activity feed in middle row
- Show all jurors in scrollable workload list (not just top 5)
- Filter recently reviewed to exclude rejected/not-reviewed projects
- Filter transition audit logs from activity feed
- Remove completion progress bar from stat tile for equal card heights
- Fix all Tremor charts: switch hex colors to named palette (cyan/teal/emerald/amber/rose)
  to fix black bar rendering
- Fix transparent chart tooltips with global CSS overrides
- Remove tilted text labels from cross-round comparison charts
