Documentation

WEBUI-1786: storage for the Web UI administrator announcement banner.

The banner is held in a single directory entry whose id is `announcement`. A directory is used rather than a document so that the value is invisible to document navigation/search, and so that the platform's default directory security applies: every authenticated user can read the entry (the banner has to render for all users) while only administrators can write it.
