Separate client and server port args for `configure` (and others)

[Aptimex]

Currently there's no way to specify both a client and server listening port when running configure, only always has to be manually set in the configs/CLI/args if you don't want to use the default 51820.

Separating these into two explicit arguments (across all the other commands as well) will also make it easier to clearly document how --outbound works, especially in relation to default behaviors when port values are not explicitly set.

May also consider adding something like --outbound-endpoint to avoid having to dynamically change the --endpoint behavior when --outbound is set.
