- Implemented `_sanitize_error` method in `DataCollectionService` and `CollectorManager` to prevent leaking internal error details.
- Improved error handling across various methods by catching specific exceptions and logging sanitized messages with `exc_info=True`.
- Added file permission validation in `ServiceConfig` to ensure secure configuration file handling, including detailed logging for permission issues.
- Refactored logging practices to enhance clarity and maintainability, ensuring consistent error reporting.
These changes significantly bolster the security and robustness of the data collection services, aligning with project standards for error handling and maintainability.
