feat: port vhost proxy :report subcommands to golang

The bash :report implementations for the caddy, haproxy, openresty, and traefik proxy plugins are replaced with a compiled golang binary that collects report keys in parallel and marshals json directly. The traefik dns-provider values keep their masking behaviour, remaining hidden in the default stdout report while surfacing for --format json or an explicit flag query. These four plugins previously had no unit tests, so a bats suite covering the report matrix is added for each.
