Refactor event processing in tests for chronological order

- Updated test files to collect events first and sort them by their CreatedAt timestamp before processing, ensuring events are handled in chronological order.
- Removed redundant error checks for scanner errors after event processing.
- Enhanced clarity and maintainability of event handling in tests across multiple files, including export, fetch, and query tests.
- Adjusted expected index counts in tests to reflect changes in event structure and processing logic.
