Refactor: Improve content error handling and presentation

-   Extracted subtitle and title logic to the `ContentError` composable
-   Used optional `contentErrorConfig` for title in the `ContentScreen` composable
-   Removed unnecessary `ErrorTitle` composable
-   Renamed `doAll` to `signAndSaveDocument` in `SuccessViewModel` and `SuccessInteractor`.
-   Updated `SuccessInteractorDoAllPartialState` to `SuccessInteractorSignAndSaveDocumentPartialState`.
-   Updated `Event.DoAll` to `Event.SignAndSaveDocument`.
-   Updated `SuccessScreen` to use the new event name.
-   Removed unnecessary `isLoading` property in the `State` class of `ViewDocumentViewModel`.
-    Removed unused `LoadingStateChanged` class in `Event` of `ViewDocumentViewModel`
