Subject: [PATCH] Use generated types and remove duplicates

Replace local duplicate model/session types with imports/exported types from generated files. Reorder imports, re-export model, remote session and session-fs related types, and export SessionEvent. Remove redundant local interfaces (ModelCapabilities, ModelInfo, ModelPolicy, ModelBilling) to centralize type definitions in generated/rpc and generated/session-events.
