Refactor MultipleChoiceTaskFragment to use a dedicated Compose-based screen

- Extract the multiple-choice task UI into a new `MultipleChoiceTaskScreen` Composable.
- Migrate `MultipleChoiceTaskFragment` to use `createComposeView`, integrating `MultipleChoiceTaskScreen` for rendering.
- Update the fragment to delegate action handling and footer position updates to the new screen component.
- Move the task body rendering logic from `MultipleChoiceTaskFragment` to `MultipleChoiceTaskContent`.
- Replace `MultipleChoiceTaskFragmentTest` with `MultipleChoiceTaskScreenTest`, migrating tests to use `composeTestRule`.
