Allow Frontend To Be Hosted On Other Domain Names

The Vite configuration has been updated to use
the `VITE_DOMAIN_NAME` environment variable for
the host in both the server and preview sections.
Now, if the `.env` file sets
`VITE_DOMAIN_NAME=0.0.0.0`, the frontend will be
exposed on all network interfaces.
