    [OPIK-3810] [BE] Fix JSON serialization for complex objects in Python online scoring (#4713)

    • [OPIK-3810] [BE] Fix JSON serialization for complex objects in Python online scoring

    When extracting nested JSON objects from trace data for Python evaluators,
    the code was using Java's toString() method which produces {key=value} format
    instead of valid JSON {"key":"value"}.

    This caused json.loads() to fail in Python with:
    JSONDecodeError: Expecting property name enclosed in double quotes

    Fix: Added serializeToJsonString() helper that properly serializes complex
    objects (Maps, Lists) to JSON while preserving simple types (String, Number,
    Boolean) as-is for backward compatibility.

    This also improves LLM-as-Judge by providing cleaner JSON format in prompts.

    • Revision 2: Add test for Python evaluator JSON serialization

    Added testToReplacementsProducesValidJsonForComplexObjects to verify that
    toReplacements() produces valid JSON for complex nested objects, which is
    what Python evaluators receive directly (without Mustache rendering).

    This addresses the code review feedback to add a test verifying valid JSON
    is sent to the Python scorer.
