Embeds assets as base64 strings in Twig

Adds Twig functions to generate base64 encoded data URIs for assets.
This allows embedding images directly into HTML, reducing the number of HTTP requests and improving page load times.

Also fixes an issue where the `FileStatusEnum` value was not being correctly accessed in the `DownloadProvider`.
