Clickable container port links (0.11.1)

Published container ports on the stack Overview (local + remote) render as
clickable chips that open the service at the host's address + port in a new
tab. New ContainerPorts component: links to the bound host IP when concrete,
else the host you're viewing from; remote stacks link to the agent host
(derived from the agent URL). http by default, https for 443/8443.
