Subject: [PATCH] Add AnyResultViewQuery to check for matching ResultView

Introduced AnyResultViewQuery and its handler to determine if any ResultView entity exists matching optional filters (Id, ActionId, ProfileId, BatchId). The handler builds the query dynamically and uses AnyAsync for efficient existence checks.
