Destroy

Unified view for single prompt operations (retrieve/update/delete). Supports both JWT (dashboard) and API key (public API) authentication. Superadmin: Can READ any prompt across all organizations via JWT. Can WRITE across organizations via JWT with an active staff_write:prompts (or broad staff_write) scope. Regular users: Can only access prompts in their organization. JWT auth uses pk lookup, API key auth uses prompt_id (partial match).
