Transition the asset state

Módulo Assets

POST/asset-units/{id}/transitionsassetUnits.transition

Moves the asset lifecycle to another state through its transition RPC, which writes the transition ledger. Uses compare-and-set on `expected_state`; a disallowed transition returns a 422 refusal. Requires `Idempotency-Key`; a replay returns the original response. A rule that refuses the request returns 422 with `refusal` and `reason`.
