Promote a signer to admin in place of an admin
Makes the signer an admin in place of the admin named in demoteSignerId, in one ceremony: the signer becomes an admin and the named admin becomes a signer. A business has exactly 2 admins, so demoteSignerId is required (409 ROOT_AT_CAPACITY_SWAP_REQUIRED without it) and must name one of the customer’s admins (409 DEMOTE_TARGET_NOT_IN_ROOT). Returns the ceremony id; completion is tracked via the wallet_signer.promoted / wallet_signer.demoted webhooks.

Headers
Caller-generated unique key that lets the server safely replay this request. The original response is returned for 30 days on any retry with the same key from the same organization, with the response header Idempotency-Replayed: true. Required on every state-changing money-moving or resource-creating POST.
