[Fonts] Migrate CardText surfaces to theme font role (#7538)

* [Fonts] Migrate CardText surfaces to theme font role

* [Fonts] Keep CardText call sites on the app font and fix px sizes

- CardText's unset fallback is qApp->font() again: only the three counter
  painters (paintNumberEllipse, GeneralCounter, PlayerCounter) were Serif
  before the role existed, and they now ask for it through
  ThemeManager::cardTextFont(). Card names, player names, counters, the
  overlay, the Archidekt and EDHREC labels and the completer delegate keep the
  app font they used before.
- Use setPixelSize for the EDHREC card name (20px) and commander name (28px)
  and details (16px) sizes: the stylesheets said px, and setPointSize made
  them about a third larger.
