Pull request overview

Updates the projection Camera template to support per-engine axis sign conventions and adds unit tests to validate extracting view angles/origin from a view matrix across multiple engine camera types.

Changes:

• Introduce projection::CameraAxes as a non-type template parameter to control forward/right inversion, and use it in get_forward(), get_right(), and new view-matrix extraction helpers.
• Add Camera::calc_view_angles_from_view_matrix() and Camera::calc_origin_from_view_matrix() plus extensive unit tests covering these behaviors (Source + Unity) and basis vectors (multiple engines).
• Update engine camera typedefs to the new Camera template parameter order and set appropriate axis inversion flags (Unity/OpenGL forward, Unreal right).

This PR includes changes to IDE inspection severity settings in .idea/editor.xml, which appear unrelated to the camera upgrade and can create noisy diffs/team-wide IDE behavior changes. If this wasn’t intentional, consider reverting these .idea changes or moving them to a separate PR focused on IDE configuration.

[Copilot]

Similar to the earlier hunk: updating .idea/editor.xml inspection severities (e.g., enabling new warnings) is likely orthogonal to the camera feature work. If the intent is just camera behavior changes, please drop these IDE config edits or split them into a dedicated tooling/config PR.

[Copilot]

Another IDE-severity-only change in .idea/editor.xml that doesn’t seem tied to the camera upgrade. Consider reverting/splitting these to avoid unrelated configuration churn in this PR.
