Enhance worker configuration and error handling for AI summarizer

- Added `TranslationEnabled` and `TranslationInterval` fields to the worker configuration to manage automatic translation scheduling.
- Updated the worker initialization to log when the translation worker is disabled.
- Improved error handling in the AI summarizer client by introducing `APIStatusError` for better context on API failures, replacing direct error messages with structured error responses.

This update enhances the configurability of the worker and improves error reporting for AI service interactions, contributing to better maintainability and user experience.
