feat: Update AI analysis and alert processing for improved email thread management

- Increased the maximum number of messages analyzed in the `analyze_thread` function from 4 to 6 for better context.
- Enhanced the system prompt to clarify the criteria for determining if a thread is actionable.
- Improved logging in the `process_alerts` function to provide detailed insights during alert processing.
- Refactored the WhatsApp sender to include better error handling and logging for Twilio integration.
- Updated email ingestion logic to return whether analysis is needed based on the folder processed.
