feat: live gRPC pages — drop mock data, talk to the real hub

Browse source 
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.

Bumps fai_studio 0.1.0 -> 0.2.0.
