feat: move auto-updater to Settings > Updater; collapse Proxmox nav by default

- Restore Settings/Updater.tsx with channel selection and update check UI
- Strip updater state/functions/Card from Settings/Proxmox.tsx; update description
- Add Updater to settingsItems and /settings/updater route in App.tsx
- Replace always-open Proxmox NavLink with accordion toggle (expandedSections state)
- Add ChevronDown/RefreshCw to lucide imports; promote useLocation from void call
