Default port not applying on MacOS Catalina

[sapphirecat]

A "minimal" config failed to work for me this morning:

[servers.dev]
address = "192.168.56.2"

[[rules]]
# ...

It produced this enigmatic error message:

dial tcp 192.168.56.2:0: connect: can't assign requested address

Note that the port is zero, rather than 80 or 443. Adding the http_port and https_port configurations to the config file made it work correctly.

Likely cause: pelletier/go-toml/v2 dropped support for default struct tags. The ports (80 and 443) are set via the default. ETA: We can set the defaults of the top-level struct, but we can't set defaults on interior structs (like the servers) as we unmarshal. We will have to recurse through the results, and fill in defaults for all zero values where that is actually invalid. Such as, but not limited to, HTTP/S port numbers.
