feat(export): enhance export functionality with new download method and configuration updates

- Introduced a new function to open export downloads in a new tab, improving user experience for task downloads.
- Updated the export job service to use more precise checks for task expiration, enhancing reliability.
- Modified the .gitignore to include temporary files, ensuring a cleaner project structure.

These changes streamline the export process and improve the management of temporary files.
