refactor[Logger]: replace console logging with logger service (#8271)

* refactor: replace console logging with logger service across multiple components

- Updated various files to utilize the logger service instead of console.log for improved logging consistency and error tracking.
- Enhanced logging levels to better categorize messages, including debug and error levels.
- Refactored logging in components such as ApiClientFactory, KnowledgeService, and MemoryProcessor to align with the new logging standards.

* refactor: update logging level in App component from error to info

- Changed the logging level in the App component to provide a more appropriate context for initialization messages, enhancing clarity in the logging output.

* refactor(logging): replace console.log with logger service in middleware and update ESLint comments

- Updated the logging implementation in the createSimpleLoggingMiddleware function to use logger.debug and logger.error instead of console.log and console.error for improved logging consistency.
- Added eslint-disable comments for restricted syntax in preload and useAppInit hooks to suppress warnings.
