Search and tags look through the Archive, and archived cards say so

A search or a tag filter on the main board, and a tag's own view, now
list every note not in Trash (a new `all` board view on the server and in
the core), so finished work can still be looked up. Archive and Trash
keep a search inside themselves.

An archived note met anywhere but the Archive carries an "Archived" chip
at the top of its card, on the web and on Android.

Task #6315.
