Highlight a club menu while its match is on or about to start

The rail entry showed a plain hit count, which says nothing about whether
that hit is happening now or six hours from now. It now turns into a red
dot with "läuft" while a match is running, and an accent dot with "gleich"
within half an hour of kick-off — the only two moments where the menu is
worth interrupting for. A one-minute ticker re-evaluates it so the state
appears on its own.
