fix(screens): wrap step subtitles to column width

Long step subtitles ("This will connect your phone to the WeVisto" /
"This will open the WeVisto setup page") overflowed the left column
and crossed the centre divider on both panels. Added a greedy word-
wrap helper and bumped step_pitch (13.3: 92→112, 7.3: 32→50) so the
wrapped second line has room below the first.

Regenerated both panels' setup_bg/ap_bg/ap_bg_retry assets.
