feat(tauri): move-to-list, rename, group toggle, keyboard shortcuts, WebDAV fix

- TaskDetailView: 'Move to...' submenu in kebab menu
- TasksScreen: list rename (inline input), group-by-due-date toggle,
  global Escape key handler for closing overlays
- SettingsScreen: auto-populate WebDAV URL/credentials on open
- SetupScreen: add window dragging, minimize/close buttons, 'Open
  Existing Folder' button
- Store: moveTask, renameList, setGroupByDueDate methods + fs-changed
  event listener for file watcher
