Refactor components and implement generation state management

- Updated import order in App component for consistency.
- Enhanced Sidebar component with loading indicator for audio generation state.
- Integrated generation state management using Zustand in GenerationForm and Sidebar.
- Improved ProfileList component formatting for better readability.
- Added new generationStore for managing audio generation state across components.
