viewer: Pan + ZoomExtents + 표준 뷰 단축키

Browse Source 
camera.rs:
- pan(dx, dy): Shift+중간버튼으로 target 이동 (화면 평면 이동)
- zoom_extents(mn, mx): E키로 전체 씬 맞춤
- set_standard_view(StandardView): 축 고정 뷰
- StandardView: Top(7) / Front(1) / Right(3) / Left(4) / Iso(Home)

lib.rs:
- shift_pressed 추적 (ModifiersChanged)
- Shift+중간버튼 드래그 → pan
- E → ZoomExtents
- 1/3/4/7/Home → 표준 뷰 스냅
- scene_mn/mx 저장 → zoom_extents에 전달
