This commit introduces a comprehensive cookie consent management system by integrating the `fxCookiesAllowMarketing()` function across multiple files. It ensures that marketing-related scripts, such as Facebook Pixel and Google Analytics, are only executed if the user has consented to cookies. Additionally, it enhances the cookie consent UI in `inc_footer.php` and `inc_header.php`, improving user experience and compliance with privacy regulations. The changes also include refactoring of cookie handling functions for better maintainability.
