UI improvements: responsive layout, unified panels, credit legend

- Add responsive 2-panel layout (mobile single-col, tablet/desktop grid)
- Unify specialization ranking with credit bars, status badges, and
  expandable allocation breakdowns (remove standalone ResultsDashboard)
- Inline decision tree ceiling data on course buttons with spec counts
- Add Clear All button to reset all course selections
- Add collapsible CreditLegend explaining bars, badges, and limits
- Extract ModeComparison and MutualExclusionWarnings to Notifications
- Add useMediaQuery hook with matchMedia-based breakpoint detection
