fix: Enhance error handling and logging across multiple evaluators

- Added logging for file retrieval and error handling in file.py, improving robustness during file operations.
- Implemented checks for file existence and parsing errors in general.py, enhancing reliability in JSON/YAML processing.
- Improved table comparison logic in table.py with detailed error logging for sheet loading and cell value reading.
- Enhanced metrics evaluation in slides.py with additional checks for paragraph and run counts, ensuring thorough comparison.
- Updated utils.py to include file existence checks and detailed error logging during cell value reading.
