fix(log): Logging System Improvements and Error Handling Enhancements (#994)

* fix: Added logging to exception handling

Added detailed error logging to exception handling across multiple files, including exception information and stack traces, to facilitate troubleshooting.

* refactor(logging): Standardize logging output methods

Replace existing debugPrint and lprint with Loggers.app.warning to enhance logging consistency and maintainability.

* refactor: Remove redundant debug log prints

Clean up unnecessary log print statements in debug code

* feat(i18n): Added internationalization support for the logging feature
