This PR improves UI ClickHouse query efficiency by adding new routes and handlers for inference metadata, updating frontend components to use these routes, and implementing cursor-based pagination.

• Backend:
  • Adds GET /internal/inference_metadata and GET /internal/episode_inferences routes in internal.rs.
  • Implements list_inference_metadata in inference_queries.rs to query inference metadata efficiently.
  • Adds InferenceMetadata and ListInferenceMetadataParams structs in inferences.rs.
  • Adds get_inference_metadata_handler in inference_metadata.rs to handle new route.
• Frontend:
  • Updates FunctionInferenceTable.tsx, VariantInferenceTable.tsx, and InferencesTable.tsx to use InferenceMetadata.
  • Modifies route.tsx files in function and variant directories to use listInferenceMetadata for fetching data.
  • Implements pagination logic in pagination.ts for cursor-based navigation.
• Tests:
  • Adds E2E tests in inference_metadata.rs to verify new endpoint functionality.
• Misc:
  • Updates package.json version to 2025.12.2.
