feat(bgp, vxlan, ospf): enhance server data handling and introduce new routes

- Added support for fetching and displaying server data in BGP, VXLAN, and OSPF pages, improving the overall user experience.
- Introduced new backend routes for OSPF and VXLAN, allowing for better data management and retrieval.
- Implemented mapping functions for backend server data to frontend types, ensuring consistency across components.
- Enhanced the sidebar to display counts for BGP sessions, VXLAN tunnels, and containers, providing users with quick insights into their network status.
- Updated tests to cover new functionalities and ensure reliability.
