Prefixes the association name with "#<folder>" in the list table and
the detail page title, and adds an editable field for it in the edit
dialog - needed since some associations are missing it (NAS folders
that were never numbered), which is what silently blanks their
ratification code on the attestato.
Verified live: table and detail title show "#2 ENCAP ODV", the edit
field reflects the current value, and saving a new value updates both
immediately.
