fix: show 0-0 for live matches with no score data; exclude live from recent

MatchCard: display '0–0' instead of '?–?' when a match is live but
score_ft_home is still NULL (sync hasn't picked up the score yet, or
Wikipedia hasn't been updated — every match starts at 0-0).

recentMatches resolver: fetch limit*2 rows then filter out live matches
so a match with score_ft_home=0 that is still in progress doesn't appear
in both the live section and recent results simultaneously.
