refactor(MCPSettings): update navigation and enhance scroll position handling

- Updated navigation logic in `useMCPServers` and `McpServersList` to use server IDs in the URL for better routing.
- Implemented scroll position memory in `McpServersList` to enhance user experience when navigating back to the server list.
- Adjusted route parameters in `MCPSettings` to retrieve server IDs from the URL, improving data handling and clarity.
