feat: add LiveMapPage for real-time vehicle tracking and ScheduleCenterPage for schedule management

- Implemented LiveMapPage with vehicle tracking using Leaflet and real-time updates.
- Added vehicle icons, status labels, and filtering options for routes.
- Created ScheduleCenterPage to display schedule versions, conflicts, and gaps.
- Introduced responsive design for both pages with dedicated CSS styles.
- Integrated API calls for fetching routes and vehicle data.
