test: enhance GLM-4.6-turbo tests with compile-time assertion and exact value validation

- Add compile-time assertion ensuring GLM-4.6-turbo is part of ChutesModelId
- Update test to use modelId variable for better type safety
- Add comprehensive validation of all model properties with exact values
- Change description formatting to multi-line style for consistency
