Modeling, Bnd_Box - CornerMax incorrect realisation (Open-Cascade-SAS#664)

- Fixed the logical error in `CornerMax()` method by correcting the openness condition checks
- Added comprehensive GTest suite for `Bnd_Box` class to prevent similar regressions
- Minor code formatting improvements in the `DumpJson()` method
