Refactor audio generation components and improve debugging capabilities

- Introduced useGenerationForm hook to streamline audio generation form handling, including validation and model download management.
- Updated FloatingGenerateBox and GenerationForm components to utilize the new hook, enhancing code organization and reducing duplication.
- Replaced console logging with a debug utility for better logging control during audio playback and generation processes.
- Improved error handling in HistoryTable and MainEditor components by integrating toast notifications for user feedback.
- Adjusted audio recording duration limits across various components for consistency.
