feat: implement file/directory move functionality

Replace fake move implementation with actual functionality using the existing rename API.
The move feature now properly moves selected files/directories to chosen destinations.

- Use existing /api/rename endpoint to move files by renaming paths
- Handle multiple file selection with sequential move operations
- Add comprehensive error handling for partial failures
- Show detailed success/failure toast notifications
- Refresh page after successful moves to display changes
