Match the News list rows and filter chips to D8's exact spec

Pulled the literal markup from the design canvas (RosterChief Platform.dc.html)
rather than the prose summary: filter chips are 28px/6px-radius with a dark
ink background when active (not the club accent colour, and not a pill/
button shape), and each row is D8's real three-line anatomy -- status pill +
mono meta on their own line, a 20px condensed headline, then a muted author/
audience line -- not the single dense line from the last pass. It reads as a
list because rows are plain hairline-divided strips (#EEF0F3, exactly this
app's --color-rule), not because the type was shrunk.
