feat(dxped): the announced DX, judged against your own log

A DXpeditions tab holding the two feeds the DX world announces itself
on: NG3K's ADXO (structured — dates, entity, calls, bands, modes, QSL
route) and DX-World's headlines. What a logger can say that a news
reader cannot is whether the operation is worth chasing, so every
announcement is put through the SAME verdict the cluster paints on a
spot — one badge, strongest wins, dimmed when the need is only a missing
QSL — with an 'only what I need' filter. One click watches every
callsign of an operation; the news headlines are mined for callsigns so
they can be watched the same way.

Parsers ported from DXHunter's and pinned with table tests against real
feed text: the 'as PJ2/W2APF' mining, the DXCC-prefix-first
normalisation without which no spot ever matches, both ADXO date forms,
and the '160-6m' span whose unit is written once (DXHunter read that as
6m alone and lost the low end).

Watchlist membership now announces itself app-wide, on the same card as
a new version: the bindings emit watchlist:changed, so a call added from
the cluster or this tab is confirmed where the operator is actually
looking — the panel's own inline message never was.
