## 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`.

## Detailed Description of the Pull Request / Additional comments
I added a new file, `Commands/UninstallApplicationCommand.cs`, which
implements the logic to uninstall applications directly from the Command
Palette. The command differentiates between UWP apps and Win32 programs.
All common error scenarios are properly handled and logged to ensure
reliability and traceability.
Additionally, in `Icons.cs`, I included the "Delete" icon from the
Windows Start menu to be displayed alongside the uninstall commands in
the Command List, providing a familiar visual cue for users.
The uninstall commands have been integrated into the appropriate classes
for both UWP and Win32 applications, making them fully accessible and
consistent across the Command Palette.
The command can be triggered using the shortcut Ctrl + Shift + Delete
for quick access.

## Validation Steps Performed
Tested locally; currently, verification was limited to uninstalling a
UWP application, unsure of additional test scenarios.

Just standardizing built-in extensions to use a `internal sealed class
Icons` for all their non-dynamic icons.
Looks like a LOT of changes, but it's icons all the way down.
