Task: Build a Language-Dispatching Router for a New Endpoint

Context

You are adding a new code_review endpoint to the codeflash-internal aiservice backend. The existing optimization and testgen endpoints both follow the same pattern: a Django-Ninja router that dispatches to language-specific handlers based on a data.language field. Imports are kept lazy (inside the function body) to avoid circular dependencies.

The endpoint should be registered at /ai/code_review and follow the same conventions as the existing 12 endpoints in aiservice/urls.py.

Task

1. Write a Django-Ninja router module code_review_router.py that:

   • Creates a NinjaAPI instance named code_review_api
   • Has a single POST / endpoint that is async def
   • Accepts an AuthenticatedRequest and a request body schema
   • Dispatches by data.language:
     • "javascript" or "typescript" calls a JS/TS handler
     • "java" calls a Java handler
     • Default (Python) calls a Python handler
   • Uses lazy imports inside the function body
   • Returns typed response schemas: response={200: SuccessSchema, 400: ErrorSchema, 500: ErrorSchema}

2. Write a request schema CodeReviewSchema (inheriting from ninja.Schema) that includes:

   • source_code: str
   • trace_id: str
   • language: str with a default of "python"
   • review_depth: str with a default of "standard"

3. Show how this endpoint would be registered in aiservice/urls.py alongside the existing endpoints.

Expected Outputs

• A code_review_router.py module following the codeflash conventions
• A CodeReviewSchema class
• A URL registration snippet
