Only run federation on 8448 and client on 80

This disables federation on the 80 port, as it's
not necessary. We also disable the old Angular webclient.

For the federation port (8448), we disable the client APIs
as those are not necessary. Those can even cause trouble
if one doesn't know about them and thinks that guarding the client
APIs at the 80 port is enough.
