fix(tv): match season-select card font sizes to other TV sheets

The season title used typography.body (40) — larger than the sheet's own
heading — and the episode count used callout. Other TV cards/sheets use
callout for the primary label and callout-4 for secondary text. Align the
season card to that convention.
