The embedded UI was served without any cache header, so a browser or a
proxy could keep an old app.js after an update (seen with the API token
display). Each file now has an ETag (hash of its content, computed at
startup); the page, app.js and style.css are sent with "no-cache", so
each load costs a 304 without body until the next version. Fonts are
cached for 30 days.
