refactor: improve comment posting logic with enhanced error handling and stability checks

- Updated the PostComment method to include error handling for navigation and element interactions.
- Replaced sleep calls with more reliable wait mechanisms to ensure page stability.
- Added checks for the presence of input elements and improved logging for better debugging.
