fix: use keyboard-selected suggestion in Autocomplete onSubmit

Resolve the active suggestion before calling onSubmit and onChange in
onKeyDown, so Enter submits the highlighted item instead of stale typed
text. Update RestConsole onSubmit to sync the provided endpoint to state
before making the request.
