Corrects the NDC calculation in `world_to_screen` to improve accuracy. Replaces custom perspective projection matrix calculation with `omath::mat_perspective_right_handed` for correctness and consistency. Updates test cases and provides debugging information by printing view and projection matrices. Addresses an issue in the feature/ndc_invalid_calc_fix branch.
