CLAUDE: Refactor ManualOutcomeSubmission to use PlayOutcome enum + comprehensive documentation
## Refactoring
- Changed `ManualOutcomeSubmission.outcome` from `str` to `PlayOutcome` enum type
- Removed custom validator (Pydantic handles enum validation automatically)
- Added direct import of PlayOutcome (no circular dependency due to TYPE_CHECKING guard)
- Updated tests to use enum values while maintaining backward compatibility
Benefits:
- Better type safety with IDE autocomplete
- Cleaner code (removed 15 lines of validator boilerplate)
- Backward compatible (Pydantic auto-converts strings to enum)
- Access to helper methods (is_hit(), is_out(), etc.)
Files modified:
- app/models/game_models.py: Enum type + import
- tests/unit/config/test_result_charts.py: Updated 7 tests + added compatibility test
## Documentation
