revert(dxped): no chase badge on the news pane

Tried it, looked at it, took it out. A headline names no band, so the
only honest verdict is entity-level — and a pane where every row reads
NEW DXCC or worked says nothing an operator can act on. Two words
repeated forty times is noise wearing the clothes of information.

The announcements pane keeps its badge, where the announced bands and
modes make the verdict specific enough to be worth a colour. The news
pane keeps what it is good at: what is happening, and a Watch button.
Changelog entry withdrawn with it — it never shipped.
