fix(adapters): stable sort order, npm/local icons, reinstall dialog, HMR polling on WSL

- Sort GET /api/adapters alphabetically by type (reload no longer shuffles)
- Show red Package icon for npm adapters, amber FolderOpen for local path
- Add reinstall confirmation dialog with current vs latest npm version
- Enable Vite polling when running on /mnt/ (WSL inotify doesn't work on NTFS)
