feat(bandmap,dxped): drop the ctrl+wheel zoom, badge the news

ctrl+wheel is the WINDOW zoom everywhere else in OpsLog, and one gesture
that resizes the whole app over one panel and one band map over another
is a gesture nobody can trust. The + and - buttons keep the zoom, and
the footer hint stops advertising what is gone.

The DX-World headlines now carry a chase badge like the announcements —
but ENTITY-LEVEL only. A headline names no band, and asking the slot
question without one answers 'new band' for every entity ever worked:
the one mistake that costs a QSO. So the news says NEW DXCC or worked,
and the sharper verdicts stay where the bands and modes are known.
