🚀 Refactor JS code to separate .js files

[arcane-engine]

Currently, all JavaScript code resides within the HTML templates. To improve maintainability and organization, we need to refactor the code so that all JavaScript lives in separate .js files under the static/js directory.

Tasks

1. Create a static/js directory if it doesn't exist.
2. Move any inline JavaScript from the HTML templates to separate .js files.
3. Ensure that the HTML templates reference the new .js files correctly.

Affected Files

• templates/base.html.jinja2
• templates/index.html.jinja2
