Fix TypeScript errors in test files

- Add missing 'src' property to OpeningMetadata test fixtures

- Add missing 'id' and 'description' properties to Personality test fixtures

- Add missing 'isPlayerWhite' property to EvaluationBar test cases

All tests now pass TypeScript validation. No changes to production code.
