fix(watchlist): judge generic DATA spots at digital-class grain; tidy the toolbar wrap

7.0589 falls in the band plan's generic [7.04-7.1] DATA segment — an F/H
DXpedition off the standard dials — and 'DATA' is in nobody's log, so the spot
read NEW MODE / Needed while the FT8 contact sat right there. A generic mode
cannot be matched exactly; it is now judged at digital-class grain — worked if
ANY digital mode of that call is logged on that band — against a second
class-folded slot set built beside the exact one (shared when the grouping
option already folds them). DXHunter answers this with a finer frequency table,
which fails on exactly these off-dial expeditions; the class rule cannot.

The toolbar also wraps as a whole with tighter gaps instead of dropping its
last filter chip onto a lone second line.
