Verify Flux SDK synchronization with Docs

[Copilot]

The Docs sync referenced Flux. The current openapi/flux.json contract was compared against the Python, TypeScript, and Go SDK providers.

• Flux contract verification

  • Confirmed /flux/images and /flux/tasks paths match.
  • Confirmed request fields, required parameters, action/model enums, and task handling match across all SDKs.
  • Confirmed the referenced Docs commit changes only the Flux guide, not the OpenAPI schema.

• Result

  • No source or test changes are proposed because all implementations are already in sync.

• Fixes sync: update from Docs (be603c4 docs: sync from PlatformBackend [automated]) #586
