Fix user gallery job pagination logic and add test for empty submission pages

- Updated pagination condition in `user_gallery_job.rb` to break when the number of pages is less than or equal to the current page.
- Added a new test case in `user_gallery_job_spec.rb` to handle scenarios with empty submission pages, ensuring no new records are created.
- Introduced a fixture file `api_search_empty_submissions.json` to simulate API responses with no submissions.
