Add docs for adding a new route to the creator API

[Chucks1093]

Summary
The process for adding a new route to the creator API, including registration, validation, middleware, and testing requirements, is not documented. A step-by-step guide reduces the onboarding time for contributors adding their first endpoint.

Scope

• document the steps to add a new creator route from registration to deployment readiness
• cover route registration, query validation, middleware wiring, and the minimum required tests
• provide a minimal working example of a new read-only route

Acceptance Criteria

• the guide covers all required steps for a new creator route
• a minimal working example is included
• no code changes are required; this is a docs-only issue

Hi maintainer, I’d create a contributor-focused guide that walks through the complete process of adding a new creator API route, including route registration, request validation, middleware integration, and required test coverage. I’d also include a minimal read-only endpoint example and deployment-readiness checklist so new contributors can follow a clear, end-to-end workflow without needing to inspect multiple parts of the codebase.
