fix(D010_01_aux): JSON-serialise stub body (HttpCtrl does not auto-encode dicts) 

The test passed `${entity_body}` straight to `Set Stub Reply`, but
`Load Entity` returns a Python dict and HttpCtrl's response writer
(`http_handler.py::__send_response`) only encodes the body when it is
already a `str`. A dict falls through: `len(dict)` reports the number
of keys (wrong `Content-Length`) and `wfile.write(dict)` raises
silently, so the mock sends headers only.

That made the auxiliary RetrieveEntity merge look broken — the broker
received no upstream body to gap-fill from. Verified end-to-end against
a real upstream: § 9.3.2 aux gap-fill works (local wins for shared
attrs, CSR fills the gap).

Serialise the body to a JSON string before passing to `Set Stub Reply`
so the wire payload is non-empty. Verified: `D010_01_aux` passes.
