Fix: Move DB operations to IO dispatcher in FeedbackDetailViewModel

The `loadFeedback`, `closeFeedback`, and `addReply` functions in `FeedbackDetailViewModel` were performing database operations on the main thread, which could lead to UI unresponsiveness (ANR).

This change wraps the repository calls within `viewModelScope.launch(Dispatchers.IO)` to ensure they are executed on a background thread.
