chore: migrate examples from orbit-camera script to ESM CameraControls

[kpal81xd]

Description

Migrates the remaining 79 examples from the legacy UMD orbit-camera.js script to the ESM CameraControls script (playcanvas/scripts/esm/camera-controls.mjs).

Standard swap = orbitCamera + ...InputMouse/Touch replaced by a single CameraControls (enableFly: false); distanceMin/distanceMax → zoomRange, pitchAngle* → pitchRange, focusEntity/lookAt → focusPoint. Framing corrected = CameraControls has no frameOnStart auto-fit, so the camera position + focus point were set explicitly to reproduce the original view.

Each example was rendered headlessly (WebGL2) and compared side-by-side against its original orbit-camera version.

Make sure those are manually tested, at least the paint and editor - both gaussian splatting examples, those were bit more tricky.
