Issue Summary

This is part of a PIR action item for HOT-119118.

In the HOT, the overwriting of last modification date on content trash broke some V2 APIs, affecting ecosystem customers. Reindexing a content when it is deleted is an important step of the reindexing process. Update all consumers of the deletion date to use `deleted-at` in the contentproperties table.

Expected Results

Content lastmoddate should not change on deletion and deleted-at cp should be added on deletion
