Add schema hint to /resend and reorder endpoints

Enhance GET /resend to return a helpful hint and a request schema for POST (fields: to, subject, html) and update the success message. Also reorder the root endpoints to list the prospects group first, then docs/resend/health/llm, improving discoverability of grouped endpoints.
