Sortable Email Domains table to see which mail domain are consuming the most disk space (size)

[d19dotca]

I know it's by default sorted by domain name alphabetically, which makes sense, but there's currently no way to sort by size of the mailbox data per domain on the main Email page in Cloudron.

It'd be great to have this quick quality-of-life improvement so admins who are hosting many mailbox domains can easily determine which ones are consuming the most disk space without needing to manually figure it out.

Obviously all the "outbound only" would be at the bottom of the list in that scenario.
