Extract DocumentEditLayout shared component for the PDF+form split-panel
UI, replacing the old scrolling layout on /documents/[id]/edit with the
same fixed-panel structure used by /enrich/[id]. Removes TranscriptionSection
and FileSectionEdit from the edit page; file upload/replace is now handled
by the shared layout. Delete SaveBar and FileSectionEdit as dead code.
