Detailed Description

This file provides a complete captive portal implementation for WiFi device configuration. The captive portal combines DNS redirection, HTTP server, WebSocket communication, and mDNS discovery to create a seamless configuration experience for end users.

Key features:

• DNS server that redirects all queries to the device's IP
• Async HTTP web server for serving configuration interface
• WebSocket support for real-time bi-directional communication
• mDNS advertisement for local network discovery
• Automatic client management and cleanup
• Platform-specific optimizations for ESP8266 and ESP32

The implementation follows the IExecutor interface pattern, allowing it to be integrated into task-based scheduling systems for non-blocking operation.

Example usage:

IPAddress apIP(192, 168, 4, 1);
ConfigCaptivePortal portal(apIP, [](AsyncWebSocket* server,
                                    AsyncWebSocketClient* client,
                                    AwsEventType type, void* arg,
                                    uint8_t* data, size_t len) {
  // Handle WebSocket events
});
 
if (portal.start()) {
  // Portal started successfully
  while (running) {
    portal.execute(0); // Process requests
  }
}
