Subject: [PATCH] test: add unit tests for SystemViewModel update confirm state
 toggles (#509)

Added SystemViewModelTest to provide basic testing coverage for the
openUpdateConfirm and closeUpdateConfirm methods. These methods
handle state changes within the UI without side-effects or
dependencies, so straightforward property assertions were sufficient.

This improves overall code reliability by ensuring simple UI boolean
states function predictably.
