feat(logging): enhance debug logging for message processing

Added debug logging to capture incoming, prepared, and truncated messages in the OpenAI class. Also, included logging for last messages fetched in the bot class. These additions aid in the traceability and debugging of message flows and processing errors.

Additionally, an option to log detailed error tracebacks in debug mode was implemented to facilitate better error analysis.
