feat: improve indexing logic and duplicate handling in connectors

- Enhanced Google Calendar and Composio connector indexing to track and log duplicate content, preventing re-indexing of already processed events.
- Implemented robust error handling during final commits to manage integrity errors gracefully, ensuring successful indexing despite potential duplicates.
- Updated notification service to differentiate between actual errors and warnings for duplicate content, improving user feedback.
- Refactored date handling to ensure valid date ranges and adjusted end dates when necessary for better indexing accuracy.
