fix: disable mobile drag, replace window.location.reload with router.refresh, use semantic icons

- Disable Muuri drag on mobile devices to prevent scroll conflicts
- Replace all remaining window.location.reload() with router.refresh() in settings/data, settings/general, and note-editor
- Replace duplicate X icons with semantic icons (Trash2 for fused badge, LogOut for leave share)
