程序员阿江(Relakkes) 5c5c5933f0 Preserve composer command popovers after drag-drop support
Drag-drop support made the composer panel clip overflow so the
stateful slash and file popovers still opened but were hidden above
the panel. Restore visible overflow on the drop target while keeping
the drop overlay and attachment flow intact, then lock both active
and empty composer surfaces with regression coverage.

Constraint: Drag-drop attachments must continue using the existing path-only composer pipeline
Rejected: Move slash and file menus outside the composer tree | broader portal refactor not needed for this regression
Confidence: high
Scope-risk: narrow
Directive: Do not reintroduce overflow clipping on composer panels without proving bottom-full popovers still render
