Add unit tests for JDBCTopologyQueryDAO SQL building

Add tests to verify the SQL query construction in JDBCTopologyQueryDAO, covering:

• loadServiceRelationsDetectedAtServerSide with no serviceIds: no extra filter appended

• loadServiceRelationsDetectedAtServerSide with single serviceId: and (source=? or dest=?) properly parenthesized

• loadServiceRelationsDetectedAtServerSide with multiple serviceIds: OR conditions chained correctly with proper parentheses

• loadInstanceRelationDetectedAtServerSide: bidirectional condition ((source=A and dest=B) or (source=B and dest=A)) is correctly formed

• If this pull request closes/resolves/fixes an existing issue, replace the issue number. Closes #.

• Update the CHANGES log.
