Submit sender (originator) information for a deposit parked on UNREGISTERED_ADDRESS
Two paths: register=false records sender data for this deposit only; register=true also creates a durable RegisteredAddress (at end-of-flow on Sardine APPROVE) that resolves any future deposits from the same address. First-snapshot wins — once recorded, a second submission returns 409. Returns 202 with the transaction in its post-signal state; poll GET /v2/transactions/:id for downstream updates.
