Auto-paginate on v1 UI

[matejcik]

When debuglink.press_yes() is sent, the UI will quickly scroll through all screens of the pagination before closing the current screen. This simplifies certain parts of UI tests.

It also causes a small difference in paginated tests where the scrollbar overflows the title, which did not seem worth fixing.

This also brings a small refactor of the debuglink feature that makes it simpler to register for debuglink events.

this will not be relevant anymore.

we might want to implement the same thing for UI2 though
