refactor(constants): streamline enums and enhance type annotations

This commit refactors the codebase to improve readability and maintainability by updating enums and type annotations:

- ✨ **Replaced `StrEnum` attributes**: Removed explicit type declarations for enum values to simplify the code.
- 🛠️ **Introduced `AudioExtensionsValid` enum**: Added a new enum for valid audio file extensions.
- 🔄 **Enhanced type annotations**: Updated `FAVORITES` dictionary to include specific type hints for clarity.
- 🧹 **Updated references**: Replaced outdated `AudioExtensions` usage with the new `AudioExtensionsValid`.

These changes improve code clarity, enforce stricter typing, and enhance extensibility.
