Update Apache configuration to optimize WebSocket handling and enhance security measures

This commit refines the Apache configuration for improved WebSocket support by adjusting the <LocationMatch> directive and ensuring proper upgrade handling. It also updates SSL settings and certificate paths for better security, while enhancing the organization of DocumentRoot and logging paths. These changes bolster the server's capability to manage real-time communication effectively and securely.
