Enhance data integration and transcript parsing

- Improved date parsing in fetch_and_store_chat_data to support multiple formats and added error logging for unparseable dates.
- Enhanced parse_and_store_transcript_messages to handle empty transcripts and expanded message pattern recognition for both User and Assistant.
- Implemented intelligent splitting of transcripts based on detected patterns and timestamps, with fallback mechanisms for unrecognized formats.
- Updated documentation for Celery and Redis setup, troubleshooting, and project structure.
- Added markdown linting configuration and scripts for code formatting.
- Updated Nginx configuration to change the web server port.
- Added xlsxwriter dependency for Excel file handling in project requirements.
