[Fonts] Migrate DeckList and InterfaceDefault surfaces to theme roles (#7539)

* [Fonts] Migrate DeckList and InterfaceDefault surfaces to theme roles

* [Fonts] Drop unused lambda captures in font-refresh handlers

* [Fonts] Fix pixel sizes and game overlay fonts from review

- Set the sizes the stylesheets carried with setPixelSize() rather than
  setPointSize(): home buttons (34), banner (24), home group box (20),
  the placeholder labels (14), the analytics drag handle (10), the EDHREC
  navigation buttons (24), the user info popup (11/14/11/10/11) and the
  game overlays (14/16/12). Points at 96 DPI were ~33% larger.
- The drag/total counters and tally columns keep the monospace family the
  stylesheets set, so digit widths stop changing as counts tick and
  white-space: pre stays aligned.
- applyDeckListFont() drops the cached tally rows before re-measuring, so
  previewing a larger DeckList font no longer leaves the tally clipped.
- Tally labels and the constructor/fontsChanged pairs in the shared-deck
  preview, quick setup, analytics panel, home box and public decks build
  their font once in a local lambda instead of twice.
