📄 Description

Generate a base AmneziaWG interface config with random PrivateKey,
ListenPort, junk packet settings, packet junk sizes, and magic headers.

Reuse the existing secure random implementation from genkey, avoid
overlapping magic header ranges, and skip UDP ports that are already bound.

Example of use:

$ awg genconf
[Interface]
ListenPort = 61134
PrivateKey = sLX5RYtVGRMTLNEWP2FaayLNnh71suORV/QkHNaeVF8=
