Optimize Xdebug configuration in php.ini

This change simplifies and clarifies Xdebug configuration by:
- Centralizing all Xdebug parameters in the php.ini file
- Improving parameter documentation with clear comments
- Adjusting log level to avoid excessive logs
- Retaining only essential parameters for better readability

Critical parameters (client_host, start_with_request, mode) are maintained
to ensure compatibility with VSCode and guarantee proper step-debugging
functionality.
