Pull Request Overview

This PR adds support for new string comparison operators (NOT_CONTAINS, STARTS_WITH, ENDS_WITH) to dictionary type filters in the Opik backend. The change enables more flexible filtering capabilities for JSON dictionary fields beyond the existing CONTAINS operator.

Key changes:

• Extended FilterQueryBuilder to support NOT_CONTAINS, STARTS_WITH, and ENDS_WITH operators for dictionary fields
• Added comprehensive integration tests to verify the new operators work correctly with dictionary filtering
