Adds a ⚙ icon button to the right of the AA toggle in each viewport
tile's compact toolbar. Clicking it opens a dropdown with:
- Shading submenu: Smooth Shaded / Flat Shaded / Wireframe on Surface /
Wireframe / Unlit (new ShadingMode enum driving UsdImagingGLDrawMode)
- Lighting submenu: Camera Headlight / Scene Lights + Dome Light toggle
- Show Grid and Anti-Aliasing toggles (mirrored from icon buttons)
- Bounding Box submenu: None / Per Object / All Selection
- Background submenu: Dark Gray / Black / Light Gray / Midnight Blue
ShadingMode is persisted in viewport_settings.ini alongside the existing
per-tile settings (saved on shutdown, restored on startup).

Replace LayerPanel with StageEditorPanel for full sublayer composition workflow:
- Edit target (ET) checkbox on root/session and each sublayer; pen icon header
- Dirty indicator (*) per layer; muted layers remain visible in list
- Drag-drop and Move Up/Down reordering with undo (LayerReorderCommand)
- Add existing sublayer via file dialog; create new sublayer modal
- Fixed LayerReorderCommand::ApplyOrder using full-stack indices on sublayer-local
list (silent remove failure → duplicate insert → USD _ValidateEdit error)
- Fixed muted sublayer visibility: walk GetSubLayerPaths() + FindOrOpenRelativeToLayer
+ m_layerRefs to keep muted layers alive and visible

- Replace all text buttons with SVG icon buttons (skip-back, step-back,
play-back, play, pause, step-forward, skip-end)
- Add rewind: separate play-backward button that flips direction
- Add loop mode button with submenu (Loop / Bounce / Off)
- Loop wraps at boundaries; Bounce reflects direction (ping-pong)
- Start/end frames moved to flank the scrub slider as plain numbers
- New icons: play-back.svg, loop.svg (FA repeat), bounce.svg (FA exchange-alt)
