v3.21.181

Consolidate minimalist views into one Minimal card with variants

Rename the Schedule card to Minimal and add a variant selector: fixtures (the
list, default), next (single-line next match + relative/countdown/live),
standings (plain text table) and form (recent W/D/L). One entry in the card
picker instead of several. card_type: schedule keeps working as an alias to
minimal. EN/NL labels; preview panels for each variant.
