Composes the platform's health picture in one view:
- Summary strip: 4 stat tiles for modules / approvals / audit
chain / services with semantic accent colour.
- Event-log panel: WORM-1 badge + chain status, points to the
first tampered event id when integrity fails.
- Modules & approvals panel: counts plus an "attention" pill
when approvals are pending.
- Services panel: declared services from operator config or a
helpful empty-state pointing at ~/.fai/config.yaml.
Backed by the new HubAdmin RPCs (VerifyEventChain, ListServices)
plus the existing ListCapabilities and ListApprovals. One
HubService.doctor() call fans out to all four in parallel.
Doctor is the new first destination in the sidebar — that's the
page an operator wants to land on after starting the app.

Studio's three MVP pages now pull live data from a running hub
via fai_dart_sdk. Mock fixture removed.
- data/hub.dart: HubService singleton wraps fai_dart_sdk's
HubClient and exposes UI-friendly types (ModuleSummary,
AuditEvent, PendingApproval) so pages don't import protobuf.
- pages/modules.dart: FutureBuilder against listModules,
groups CapabilityEntry rows by module, retry-on-error UI.
- pages/audit.dart: 2s polling Timer, status bar shows
"live (polling 2s)" or "disconnected — <error>".
- pages/approvals.dart: live listApprovals, Approve sends
DecideApproval(APPROVE), Reject opens a reason dialog and
sends DecideApproval(REJECT). Both refresh after success.
- Connection-error states across all pages: cloud_off icon +
hint to start `fai serve` + Retry button.
When no hub is running the pages render their disconnected
state instead of crashing. When a hub is running, the data is
real — no more mock fixture.
