Add minimalist Schedule card

A plain zebra-striped fixtures list: date, time, home – away, competition — no
logos or colours. Options: show (upcoming/previous/all), max_matches, my_team
(bold), show_competition, hide_header. Shows "unknown" for TBD kick-off times
(integration time_tbd) and the score for finished matches. EN/NL labels; added
to the preview and card registry.
