feat: enhance date handling and indexing logic across connectors

- Added normalization for "undefined" strings to None in date parameters to prevent parsing errors.
- Improved date range validation to ensure start_date is strictly before end_date, adjusting end_date if necessary.
- Updated Google Calendar and Composio connector indexing logic to handle duplicate content more effectively, logging warnings for skipped events.
- Enhanced error handling during final commits to manage integrity errors gracefully.
- Refactored date handling in various connector indexers for consistency and reliability.
