Refactor UI layout and introduce safe area constants for improved responsiveness

- Updated App, AppFrame, and AudioTab components to utilize new TOP_SAFE_AREA_PADDING and BOTTOM_SAFE_AREA_PADDING constants for consistent layout adjustments.
- Enhanced Sidebar and MainEditor components for better organization and user experience.
- Improved VoicesTab and ProfileList components by integrating new layout features and removing redundant import functionality.
- Streamlined HistoryTable and ModelManagement components for better visual consistency and interaction.
