What does this MR do and why?

This MR unblocks duo chat regression evaluator (gitlab-org/modelops/ai-model-validation-and-research/ai-evaluation/prompt-library!918 - merged) that requires expanded GraphQL query when adding an example to the regression dataset.

When expanded_ai_logging feature flag is enabled for a specific user, the incoming GraphQL query is logged in llm.log.

Example log:

{

    "time": "2024-12-16T05:28:42.490Z",

    "class": "Mutations::Ai::Action",
    "ai_event_name": "ai_action_mutation",
    "ai_component": "abstraction_layer"
}

When the feature flag is disabled:
