Subject: [feature] pixelated UA integration

a bit hacky and all, but this should launch the service
and allow interacting from the default site (localhost:9090).

this is the first example of a pyqt-js bridge, it's an interesting
mechanism that we can use more in the future.

no efforts made so far in authenticating the app.
