MgGrid — Fullscreen & Rendering

Part of the MgGrid system. See README.md for overview and component hierarchy.

Fullscreen Mode

Two modes depending on whether MgGridWithInfoPanel wraps the grid:

Scenario	Behavior
With wrapper	ToggleFullscreen() delegates to wrapper — fullscreen includes grid + InfoPanel
Standalone	Grid renders its own mg-fullscreen-overlay with header (Caption + close button) and body

Rendering

BuildRenderTree uses manual render tree building (not Razor markup):

1. Outer CascadingValue<IMgGridBase> — provides this grid as ParentGrid to children
2. If standalone fullscreen: div.mg-fullscreen-overlay > div.mg-fullscreen-header + div.mg-fullscreen-body > base.BuildRenderTree
3. If normal: div[style=display:contents] > base.BuildRenderTree
4. _gridRenderKey (Guid) used as element key — changed by ForceRenderAsync() to force re-initialization
