Problem: Saved connections lack health evidence when selecting a model, while
automatic credential-bearing checks require an explicit user opt-in.
Root cause: The previous UI slice also redesigned the disabled picker, hiding
account endpoint headings and reducing density outside the requested scope.
Fix: Preserve the original grouped rows, hosts, ordering and modelLabel behavior.
Add only short accessible health chips after reading backend consent. Put the
global switch outside the service editor, and explain unsupported older servers
and settings-read failures without enabling probes. Rebase onto current studio.
Verification: 640 frontend tests, production build, census fixtures, vet, pinned
lint, repository checks, HTTP authorization/route tests and builtin tests pass.
All 849 boot cases accounted for: 846 pass, 3 skip. Negative controls fail the
group-layout and old-server regressions. Native Electron light/dark wide/narrow
captures and 390px browser inspection verify retained row density and hosts.
Native disable/reopen issues no new requests; no generation requests occur.
