Add InvokeRecActionCommandExtensions for ISender

Introduce a new static class `InvokeRecActionCommandExtensions`
to extend the `ISender` interface with the `InvokeRecAction`
method. This method simplifies the invocation of
`InvokeRecActionCommand` by allowing callers to pass only the
`profileId`, internally creating and sending the command.
