Handle 'Body already consumed' from React Strict Mode duplicate calls

- Catch TypeError when req.json() is called on consumed stream
- Return success response for duplicate calls (first call handles the actual work)
- This handles React Strict Mode firing onClick twice in parallel
- Only the first call that successfully reads body will process the request
