fix(grafana): surface upstream error when the prefetch GET fails

waleedlatif1 · waleedlatif1 · commit cab90e75c856 · 2026-06-15T18:52:35.000-07:00
Check response.ok on the existing-resource GET in both update routes and return
the upstream status/body, matching how the tool framework surfaced GET errors
before the move to internal routes (the framework checks response.ok before
transformResponse). Without this, a failed prefetch produced a generic
'Failed to fetch existing ...' message and dropped Grafana's error detail.
