Task 13: Implement fuzzy search with fuse.js

- Installed fuse.js for fuzzy search functionality
- Created src/lib/search.ts with buildSearchIndex and groupResultsBySection functions
- Search index includes all consultations, medications, problems, investigations, and documents
- Updated ClinicalSidebar to use fuse.js instead of simple filter
- Search results grouped by section (Experience, Skills, Achievements, Projects, Education)
- Section headers show icon and count
- Each result shows title and highlight text (truncated)
- Clicking a result navigates to the section and expands the matching item
- Minimum 2 characters required for search
- Top 10 results displayed
- Clean dropdown styling with hover states
- Integrates with AccessibilityContext to set expandedItem
