dir: Return 503 code when rejecting single hop request

Browse Source 
Single hop rejection (POST and GET) for HS v3 descriptor now return a 503 code
which is more accurate code from dir-spec.txt and from other rejection case in
the code.

For instance if you are not a relay and you get a POST request, a 503 code is
sent back with a rejection message.

Part of #31958
