Task 10: Build InvestigationsView with results panel

- Created InvestigationsView component with expandable rows
- Status badges: Complete (green), Ongoing (amber), Live (pulsing green)
- Tree-indented results panel with methodology, results, tech stack
- View Results button for PharMetrics linking to medicines.charlwood.xyz
- Proper semantic table markup with scope attributes
- Traffic lights always accompanied by text labels
- Accordion behavior: only one row expanded at a time
- Height animation 200ms ease-out for expand/collapse
- Respects prefers-reduced-motion
- Updated PMRInterface to include InvestigationsView
