feat(terminal, wireguard): enhance UI components and functionality

Updated the TerminalPage to include a new ServerTileRail for server selection and added QuickCmds for quick command execution. Enhanced the WireGuardPage with new tabs for interface and peer management, improved server selection handling, and added support for displaying peer details. Refactored data grids to support compact server views and improved empty state handling. Introduced new hooks for managing server states and improved user experience across components.
