feat(web/bubblegum): allow passing status as an int

Browse source 
The whole pass the name of the status as a string thing was mostly born
out of an overeager use of yants. It is still very neat especially for
common cases like "OK", so we'll keep it, but also allow passing the
integer variant of the status as well which probably feels more natural
for a lot of people, especially over getting the casing right for
"I'm a teapot".
