Say it once, and say whose scores are hidden

A copy pass over the Finnish UI. The em-dash aside was doing the work of a
second sentence in ten places, so it is a second sentence now, or gone.

The sealed-score wording was wrong twice over: it promised "pisteet" when
only other people's are hidden, and said "kirjoitat" when the reveal
actually happens on save. Both fixed on the queue, the song page and the
card badge.
