Refactor CyberPanel installation logic to streamline PHP version handling

- Removed local installation function in favor of a direct installation approach.
- Updated installation script to prioritize the development branch for downloading CyberPanel, with a fallback to stable if unavailable.
- Adjusted PHP version lists across various scripts to exclude PHP 8.6 and ensure compatibility with existing versions.
- Enhanced error handling and feedback during installation to improve user experience.
