Support for hash-based storage in the browser for html file

[yo8z6gv]

Enable hash-based storage, similar to MEGA or Netlify, instead of "Hotlink protection enabled" for HTML files. This should allow pages to open (instead of displaying code content or showing an error about a file being too large, e.g., 90MB used: data:image/jpeg;base64,/...). This way, there is no need to use services like htmlpreview.github.io—the file will be loaded into the browser's hash storage every time via an API request for the download.
