fix: parse Wikipedia 12h time format and sort upcoming matches with NULLS LAST

Wikipedia stores match times as "6:00 p.m." (1-digit hour) which didn't
match the \d{2}:\d{2} regex, producing NULL for those matches. Introduced
parseTime12h() to handle 1-2 digit hours + AM/PM and convert to 24h.
Also sort upcomingMatches by NULLS LAST so unscheduled games appear after
timed ones rather than first. Dropped "openfootball" data attribution.
