Filer: batch deletion operations to return individual error results (#7382)

* batch deletion operations to return individual error results

Modify batch deletion operations to return individual error results instead of one aggregated error, enabling better tracking of which specific files failed to delete (helping reduce orphan file issues).

* Simplified logging logic

* Optimized nested loop

* handles the edge case where the RPC succeeds but connection cleanup fails

* simplify

* simplify

* ignore 'not found' errors here
