Fix overlay web adapter: Add standalone mode API fallback

- Added isStandaloneMode detection (window.parent === window)
- getFixtureData() now fetches directly from /api/overlay/fixtures in standalone mode
- getCompletedMatches() now fetches directly from /api/overlay/completed-matches in standalone mode
- getWinningOutcomes() now fetches directly from /api/overlay/winning-outcomes in standalone mode
- Prevents timeout waiting for parent window response when no parent exists
