Refactors camera input handling for smoother and more intuitive control.
This change introduces a dedicated CameraInput structure and updates the
camera class to use it for movement and rotation based on user input.
It removes the old position class camera related logic and integrates mouse
delta for precise rotation control and scroll wheel for speed adjustments.
Updates ImGui layout to reflect the new size for the docked space.
