feat: add vehicle tracking/GPS map

New TrackingPage with:
- Interactive map grid showing vehicle locations
- Real-time GPS coordinates (mock data)
- Vehicle speed & heading display
- Vehicle selector dropdown
- Live status indicators
- All vehicles list with speed
- Click-to-track functionality
- Location details sidebar:
  * Latitude/Longitude
  * Current speed
  * Heading direction
  * Last update timestamp
  * View history button

Features:
- Grid-based map (no external dependencies)
- Vehicle markers (color-coded selected/inactive)
- SVG grid background (lat/lng lines)
- Responsive layout (map + sidebar)
- Mantine UI + brand colors
- Mock GPS generation per vehicle

Route: /dashboard/tracking
Sidebar: "Track Vehicles" in Fleet Management
