Improve architecture handling for msstore applications

Refactors the application download logic to correctly handle packages from the 'msstore' source, which does not support architecture specification.

- The download process no longer passes an architecture parameter for msstore apps.
- The architecture selection dropdown in the UI is now disabled for msstore apps to prevent invalid configurations.
- Imported or searched msstore apps will display 'NA' for their architecture.
