🤖 Frontend-only DnD ordering for Projects sidebar (#190)

Implements drag & drop reordering of projects in the left sidebar using
react-dnd.

Key points:
- Frontend-only: order stored in localStorage via usePersistedState
(key: )
- Pure utilities for sort/reorder/normalize in 
- DraggableProjectItem wrapper + DragHandle visuals, no backend/config
changes
- Typecheck, lint, and formatting pass

Testing:
- Drag projects up/down; order persists across restarts
- New projects append to end; removed projects are pruned from order
- Expanded/collapsed state unaffected
