fix(trigger): enhance error handling and refactor end user creation in trigger workflows

- Improved error handling in `TriggerSubscriptionListApi` to return a 404 response for ValueErrors.
- Refactored end user creation logic in `service_api/wraps.py` to use `get_or_create_end_user` for better clarity and consistency.
- Introduced a new method `create_end_user_batch` for batch creation of end users, optimizing database interactions.
- Updated various trigger-related services to utilize the new end user handling, ensuring proper user context during trigger dispatching.
