Revamp Remote Monitor to support multiple users and components with improved UI

[Copilot]

Overview

This PR completely revamps the Remote Monitor application to address the core limitations of the original single-user, single-component system. The changes transform it into a robust, professional multi-user monitoring solution with significantly improved user interfaces on both desktop and mobile platforms.

Key Changes

🔗 Multi-User Server Architecture

The original server could only handle one client connection at a time. This has been completely redesigned:

• New MultiUserServer.java: Thread-safe server supporting unlimited concurrent connections using ExecutorService thread pools
• New ClientHandler.java: Individual client session management with proper authentication and data streaming
• Enhanced connection handling: Each client gets its own dedicated thread with unique session tracking and graceful disconnection

🖥️ Multi-Component Hardware Support

Previously, the system could only display one instance of each component type (CPU, GPU, RAM, Disk). Now it properly handles multiple components:

• Enhanced ComponentManager.java: Safe detection and management of multiple GPUs and storage devices
• Robust error handling: Graceful fallbacks when JSensors data is unavailable (common in virtual environments)
• Improved JSON structure: Server now sends properly formatted arrays for multiple components

🎨 Desktop Application Improvements

Replaced the basic console-only interface with a professional dual-mode system:

• New Swing GUI (ServerGUI.java): Modern desktop interface featuring:
  • Real-time server status and connection information
  • Live client connection monitoring with IP address tracking
  • Server logs with timestamps for debugging and monitoring
  • Start/Stop server controls with proper state management
• Smart mode detection: Automatically launches GUI when available, falls back to enhanced console mode in headless environments
• Command line options: --gui flag for explicit mode selection

📱 Mobile Application Overhaul

Completely redesigned the mobile interface to handle multiple components and improve user experience:

Connection Screen (Connection.xaml):

• Material Design-inspired clean interface
• Better field validation and error messaging
• User instructions and guidance
• Improved visual feedback during connection attempts

Monitor View (Monitor.xaml.cs):

• Dynamic component display: Scrollable sections for multiple GPUs and disks
• Component cards: Each hardware component gets its own detailed information card
• Real-time status: Connection status indicators and refresh functionality
• Enhanced error handling: Better network error recovery and user feedback

🛠️ Architecture Improvements

• Thread safety: Proper concurrent programming with AtomicReference and synchronization
• Resource management: Automatic cleanup of connections, threads, and resources
• Comprehensive logging: Detailed server logs with timestamps and client activity tracking
• Error resilience: Robust exception handling throughout the application stack

Example Usage

Desktop Server

# GUI mode (automatically detected if display available)
java -cp "..." com.company.Main --gui
# Console mode (works in any environment)
java -cp "..." com.company.Main

Mobile Client Experience

1. Enhanced Connection: Clear form with validation and helpful error messages
2. Multiple Component Display:
   • CPU section with usage, temperature, and fan speed
   • RAM section with usage statistics
   • GPU section showing all detected graphics cards
   • Storage section displaying all disk drives
3. Real-time Updates: Live data refresh with connection status indicators

Testing

The changes have been tested with:

• Multiple concurrent mobile client connections
• Various hardware configurations (including virtual environments with limited sensors)
• Both GUI and console modes on the desktop application
• Error scenarios including network disconnections and hardware detection failures

Backward Compatibility

The changes maintain full backward compatibility with existing mobile clients while adding support for the new multi-component features. Existing configuration files (config.json) continue to work without modification.

Performance Impact

• Improved scalability: Server can now handle multiple clients without blocking
• Better resource usage: Thread pools prevent resource exhaustion under load
• Enhanced responsiveness: Non-blocking operations improve overall system performance

This revamp transforms Remote Monitor from a basic single-user tool into a professional-grade monitoring solution suitable for multi-user environments.
