fix(web): report a failed instance list load on four console pages

Four console pages loaded the instance list with `listInstances().catch(() => setInstances([]))`, so a failed
`GET /api/instances` rendered exactly like a deployment that has no instances: an empty Select, no message,
and no way to retry.

- home/dashboard.tsx: the instance filter emptied silently while the page kept showing all-instance data.
- settings/DataSourceTab.tsx: the data-source form's instance picker emptied inside the modal.
- studio/Producer.tsx: the instance filter emptied and the Search button stayed disabled.
- studio/LiteTopic.tsx: the extend-TTL dialog opened with an empty picker, and confirming it returned
  early without a word.

A failure is now a state on each page: the Select goes into its error status, the existing
`instance.listLoadFailed` copy says what happened, and a retry re-runs the load. #4700 fixed the same shape
for the delivery filter and named the first two files as still silent; #4953 did it for the instance pages
through the shared selector. The other call sites already report a failure or retry
(pages/ops/alerts.tsx, pages/studio/BrokerCluster.tsx, pages/cluster/index.tsx, pages/instance/index.tsx).
