feat(frontend): say when a workspace holds only archived items

A workspace whose items are all archived read as empty, because the
placeholder is decided by the default listing. Reaching those items then
depended on the toolbar, which is why it had been left interactive while
dimmed — and that let a kind toggle replace the invitation with "no
items found" on a workspace that really was empty.

The state is named instead. When the default listing comes back empty,
one request asks whether anything archived exists, and the placeholder
says which of the two it is: "Everything in this workspace is archived"
with a link to show them, or the ordinary invitation. Held until that
answer lands rather than drawn and swapped, since the wrong one claims
the workspace is empty when it is not.

The toolbar is dimmed and `inert` again, its original design: the
archived case now carries its own way in.
