Add comprehensive column sorting with icons and tooltips to RequestBreakdown

Enhance all breakdown sections (Resource Type, Status Code, Hostname) with:
- Clickable column headers for sorting by any field
- Visual sort indicators: neutral (⇅), ascending (▲), descending (▼)
- Interactive tooltips showing current sort state and available actions
- Default sort by request count in descending order
- Toggle between ascending/descending by clicking same column
- Consistent styling with brand colors and hover effects
- Proper flexbox layout for icon positioning

All 8 columns are sortable: name, count, count %, size, size %,
response time, response time %, and average response time.
