Add server status display and protocol version upgrade handling

- Introduced a new `ServerStatusInfo` class to encapsulate server status data including MOTD, player counts, and version information.
- Implemented `ServerStatusDisplay` to format and display server status information in both classic and TUI modes.
- Added protocol version upgrade logic in `ProtocolHandler` to determine the highest supported protocol version for multi-version servers.
- Updated translations to support new server status labels and messages.
- Created `ServerStatusPanelBuilder` for TUI to visually represent server status with player information and connection details.
