Fix handling of incomplete matches from past days on startup

- Add _cleanup_old_incomplete_matches() to mark 2+ day old matches as failed
- Add _get_yesterday_incomplete_matches() to detect yesterday's incomplete matches
- Add _get_or_create_today_fixture() to ensure new matches go to today's fixture
- Modify initialize() to process past incomplete matches before starting
- Modify _handle_start_game() to use pre-computed yesterday_fixture_id
- Add yesterday_fixture_id attribute to track yesterday's fixture for completion

This ensures:
- Matches from 2+ days ago are marked as failed with bet cancellation
- Yesterday's incomplete matches are played to completion first
- New matches are created in today's fixture, not yesterday's
