test: Add integration test for DELETE /api/admin/crawlinginfo/all endpoint (#2942)

Add test coverage for the crawlinginfo bulk deletion endpoint that was
previously untested. The new test verifies that DELETE /api/admin/crawlinginfo/all
successfully deletes all old crawling sessions except currently running ones.

Changes:
- Add crawlingInfoDeleteAllTest() test method with @order(3) annotation
- Add testDeleteAllCrawlingInfo() implementation that:
  * Reads crawling info logs before deletion (if any exist)
  * Calls DELETE /api/admin/crawlinginfo/all endpoint
  * Confirms all old sessions are deleted (result should be 0)
  * Works correctly even if logs were already deleted by previous tests
- Add @TestMethodOrder annotation to ensure proper test execution order
- Import necessary JUnit OrderAnnotation classes

Test execution order:
1. jobLogTest() - Job log CRUD operations
2. crawlingInfoTest() - Individual crawling info operations
3. crawlingInfoDeleteAllTest() - Bulk deletion (NEW)
4. failureUrlTest() - Failure URL operations
5. searchListTest() - Search list operations

This test follows the existing pattern in CrawlerLogTests.java and uses
the same testing approach as other admin API integration tests.

Resolves #1016
