fix(desktop): correct http capability url patterns for non-standard ports

http://** uses ** in hostname which is not valid URL Pattern spec.
Hostname wildcard is * (not **); non-default ports require the *:*
host:port form. Add all four variants to cover http/https on both
default and non-default ports.
