Don't use <label> tags for things that are not labels, add a proper
<title> for the page, add a back link, remove an unnecessary
`inline-block` style for a header, localize dates and field names, ...
The interface could be further improve: proper diffs for long texts,
better separation between fields, ...
The name of the changed field is translated, values are truncated so
descriptions with thousands of character would make this table huge and
impossible to read, dates are localized, and values like arrays and
booleans are displayed properly.
