fix: the format picker shows the format's name only — the slide count is the one length control

The picker labels carried each format's typical length ('15–25 cases, three
or four slides each, 60–90 minutes'), which sat under a slide-count field and
read as a second, contradicting number. The label is the name, the hint says
who the format is for, and the brief tells the model that the slide count
asked for is the length and the parts fit into it.
