Better slug unique warning for Documents

As editors may be editing documents with the same title we needed to
improve the functionality of this warning. This commit changes the
warning text to an alert to be more visible, disables the Publish button
if it is not unique and only makes the uniqueness check happen if the
document isn't currently Published. This means that you can still
Publish already published documents.
Better slug unique warning for Manuals

Same process as Specialist Documents. Disable the publish button if
there is a slug clash, move the warning to a banner and change the
slug check to only be displayed on the draft Manual.

Use the correct published_at date

When publishing, we first update the document to say that it is
'published', then we export it to the content api. Because by the
time the exporter calls the published_edition after the document has
been updated to published, this returns the latest_edition instead.

Instead we must find the last major edition and use its updated_at
to retain the published at date across minor updates.
