CLAUDE: Fix scorebug win probability display logic and enhance percentage positioning

Fixed critical bug where win probability progress bar displayed backwards: - Away team with 75% win probability was showing as losing - Home team with 25% win probability was showing as winning Changes: - Corrected comparison operators in create_team_progress_bar() function - Enhanced UX by positioning percentage next to winning team: * Home winning (>50%): Percentage on right (e.g., "POR ░▓▓▓▓▓▓▓▓▓► WV 95.0%") * Away winning (<50%): Percentage on left (e.g., "75.0% POR ◄▓▓▓▓▓▓▓▓░░ WV") * Even game (=50%): Percentage on both sides - Added comprehensive test suite with 10 test cases covering all scenarios - Updated docstring examples to reflect new format All tests passing (10/10) ✅ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
