feat: add scripts for dynamic content loading and embedding
Introduce global.js to streamline script loading and URL parameter parsing, enabling conditional embedding of Moodle elements. When the `embed` parameter is set to `1`, specific interface elements are hidden, and necessary scripts (jQuery and Bootstrap) are loaded to enhance form interactions and AJAX handling. Add script.js to handle dynamic content presentation within a modal. This includes script loading, modal management, and transition between content items, ensuring seamless navigation and adherence to required fields. Fosters a clean, embedded viewing experience and improves content presentation and interaction.
