Implement 301 redirects for www to non-www and enhance canonical tag handling

This commit adds 301 redirects in the Apache configuration to redirect traffic from www.tt-tagebuch.de to tt-tagebuch.de for both HTTP and HTTPS. Additionally, it introduces middleware in the backend to dynamically set canonical tags based on the request URL, ensuring proper SEO practices. The request logging middleware has been disabled, and sensitive data handling has been improved in the MyTischtennis model and API logging service, ensuring compliance with data protection regulations. Frontend updates include enhanced descriptions and features in the application, improving user experience and clarity.
