fix(catalog): keep the live catalog truthful after every import path

The live catalog store only covered part of the import surface. A durable
job settled, a sync queue drained, a .nitro upload or a clone run left the
Studio rail and the stats bar showing pre-import numbers until the page was
reloaded, and the Catalog Manager kept a second tree that never saw writes
made elsewhere in the session.

Every one of those paths now pulls the tree again, and the refresh carries
the totals with it: importing writes catalog rows server-side, so the counts
the store holds were stale for the rest of the session.

- refreshCatalogTree shares one request between concurrent callers and queues
  a single follow-up read when a write lands mid-flight, so a burst of edits
  costs at most one extra read.
- useFurnitureJobs treats its first payload as a baseline, so a page load no
  longer replays every past import as "just settled", and hands the settled
  jobs to the callback.
- The Catalog Manager pushes its own mutations into the store and re-reads its
  active tab when the store changes.
- The 30s unstable_cache on the admin totals is now tagged and invalidated from
  every catalog write, including the import worker, so it no longer survives an
  import even across a hard reload.
