Jiří Polášek 466a94eb40 CmdPal: Fix updating primary command and context menu and app icons (#42155)
## Summary of the Pull Request

This PR fixes three issues in one go:
- Restores missing icons in app context menus.
- Fixes propagation of changes from a command item to the context menu
item for the primary action.
- Ensures the context menus stay in sync when underlying command items
change.

Details:
- Correctly propagates updates of name, icon, and subtitle from a
command item to its primary command
(`CommandItemViewModel._defaultCommandContextItemViewModel`).
- Correctly propagate updates of command's name to title
(`CommandItem.ctor`).
- Fixes icon loading for application items: `AppCommand` no longer loads
an app icon by default but instead relies on the caller to provide one
(since `AppListItem` also handles icon loading).
- Adds a generic fallback icon for apps when an icon cannot be loaded.
- Updates bindings on context menu items to `OneWay`, ensuring the UI
properly reflects item changes.
- Adds a sample that showcases dynamically updated commands (with cats
and dolphins!) to _Samples → List Page Sample Command_.

⚠️ Toolkit changes:
- `CommandItem` won't capture assigned Command's name as its `Title`.
This will allow it to propagate future changes to `Command.Name`.

Pictures? Moving ones!
