* fix: portal staged-preview-modal to document.body to escape .composer stacking context

The .staged-preview-modal was rendered inside .composer (position:relative;
z-index:1), which created a local stacking context. The modal's z-index:1200
was scoped within .composer's context instead of the root stacking context,
preventing it from properly covering .app-chrome-header when active.

Fix by rendering the modal via createPortal to document.body, consistent
with other modals in the codebase (ConversationsMenu, FileViewer, etc.).
