CSNAPC-12302: SC 6.2.2 clean up secondary job does not remove backups
Issue
SC 6.2.2 cleanup secondary job does not remove backups from the repository. During cleanup, SnapManagerWeb fails to discover snapshots for cleanup due to cache and live discovery failures, falls back to legacy discovery, and returns error 105: "Unable to find snapshot information from the cache." As a result, invalid snapshot locators are logged and the cleanup job completes without deleting any backups because the snapshot list required for deletion is never loaded.
