New TeamLogo view loads bundled TeamLogos/{abbrev}.png with a UIImage
cache so scrolling doesn't repeatedly re-decode. GameRow and SeriesRow
now render [logo] TRI @ [logo] TRI with tricodes in a monospaced font
so columns line up regardless of which letters are present. SF Symbol
fallback when an abbrev has no bundled logo (e.g. "TBD" for unfilled
playoff slots).
