test(e2e): open the mood sheet's full form before measuring it

The mood sheet opens on the five-face quick check and reveals the rest of
the form, timestamp row included, once a face is picked. The dialog-overflow
spec measured the quick check instead, found no date field, and failed on
its own readiness gate rather than on the layout — a guard that cannot reach
the state it is about proves nothing either way.

It now picks a face and waits for the annotate panel, which is the state the
report describes.
