fix(hitl): Expose check_approval through database manager client

Fixed "Client is not connected to the query engine" error when
check_approval is called from block execution context. The function
is now accessed through the database manager async client (RPC),
similar to other HITL methods like get_or_create_human_review.

Changes:
- Add check_approval to DatabaseManager and DatabaseManagerAsyncClient
- Update HITLReviewHelper to call check_approval via database client
- Remove direct import of check_approval in review.py
