* test: add comprehensive tests for loadSettings in SettingsViewModel
Adds `testLoadSettings_loadsAllProperties` to `SettingsViewModelTest.kt` to thoroughly verify that `loadSettings()` correctly maps all required settings properties from `AuthManager` to the `uiState`. The test utilizes `runTest` and `advanceUntilIdle()` to properly handle testing the coroutine launch in the ViewModel's init block.
