API console and exports

• Swagger API console
  Authorize with a Feed API key; /api/monitor also supports its separate monitor key.
• OpenAPI 3.1 JSON
  Machine-readable public API contract; import it directly into API clients.
• Postman complete import package
  Primary Postman download: HTTP collection, WebSocket use cases, environment and import guide.
• Postman HTTP Collection
  All public HTTP requests; the ticket request automatically saves ws_ticket.
• Postman WebSocket AsyncAPI
  Import and generate saved /ws and /api/cell/v2/ws WebSocket use cases in Postman.
• Postman Environment
  Shared blank api_key, monitor_key and ws_ticket variables for both imports.

Swagger and Postman accept the same existing Feed API keys. A deployment with a separate monitor key requires it only for /api/monitor. Internal /internal/* control-plane routes are intentionally excluded.
