Always show "WebUI" for user specified URLs

I often specify custom WebUI URLs based on my network/local-domain
setup. I rarely if ever use "http://[IP]:[PORT:8888]/" templated URLs.

This change maintains support for the existing templated
bridged/host-network URL schema while enabling the "WebUI" affordance
for containers where the user explicitly entered a WebUI url, e.g.
"https://grafana.mylan.io"
