One endpoint for every captcha type

The scenario takes an image and a captcha type, validates the fields, routes the job to the right Captcha Sonic solver and returns the result in a single format.

• One entry point instead of a dozen separate handlers
• The response always comes back in the same shape — easy to plug in
• Fields are checked up front: a clear error instead of silence
• New types get added to the router, not to your code
