Fix function parameter and update GoRouterProxy command arguments

 - Correct the missing type for the `portToForward` parameter in `GoRouterProxy` function.
 - Update command arguments to include `--port` and `--forwardTo` flags in `GoRouterProxy`.
 - Add `GoRouterProxy` port to the `PreparePorts` function.
 - Prefix a test with `FWhen` to focus on a specific scheduler test.
