The prefix matching ported from DXHunter swallowed too much: a three-letter
special-event entry N8W lit up NEEDED for N8WCR, a different station entirely.
The implicit becomes explicit — a bare entry matches exactly that call, a
trailing star makes it a family: VK9* catches every VK9…, RI0SP* the
expedition's portable forms. A star anywhere else (or alone) is refused at Add
rather than silently matching nothing. Same rule in the backend Match and the
tab's own matcher, pinned by test.
