Fetches all scheduled World Cup fixtures from the-odds-api in one call. Group stage games default to "group" round. Use this once at tournament start.
Group stage: equal scores = Draw. Knockout: higher score advances (covers extra time/pens).
Use this to fix a wrongly entered result. Picks are preserved; scores are recalculated.
Fetches h2h odds (Team A / Draw / Team B) with implied probabilities, and scores for completed games. Normally runs at 3am ET. Costs ~3 credits (odds + scores).
Sends a daily reminder email to the first contestant only.
