feat(dapps) attempt to fix the wallet connect abstraction

Spent too much time figuring out the puzzle of
service->module->view->QML just to call a
status-go function.

Keeping this attempt for later while moving to a
simplified Controller/Provider approach. I will
come back to the abstraction when we add tests
to use it.

Updates: #14615
