feat(adminui): Test Connect button on every typed driver page

- AdminProbeService routes TestDriverConnect through
  IAdminOperationsClient with a 65s outer guard (actor side already
  clamps to [1,60]).
- Added generic AskAsync<T> to IAdminOperationsClient interface and
  AdminOperationsClient impl, delegating straight to the Akka proxy.
- DriverTestConnectButton renders the button + inline result chip,
  auto-clears after 30s, disables during in-flight.
- Wired into all 9 typed driver pages directly under the
  identity section. Sources timeout from the form's
  ProbeTimeoutSeconds; sources config JSON from the form's
  current Options (operator can test BEFORE saving).
