Subject: [PATCH] Add test for KeysViewModel state updates (#507)

Added unit tests to `KeysViewModelTest.kt` to cover `setNewKeyName` and `setNewKeyValue` functions. This ensures that the state flow correctly updates when key names and values are modified. This increases the test coverage for UI state manipulation within the Keys settings module.
