feat: enhance load_all_scales function for language support

- Updated load_all_scales to accept an optional language parameter, allowing for the loading of scales based on the specified language.
- Modified calls to load_all_scales in various endpoints to pass the user's detected language, ensuring consistent language handling across the application.
