Set a wallet's display label

Set (or clear) a wallet's server-side display label. SIWX-authenticated; the signer MUST equal the {address} being labeled (proof of control) or the call returns 403 WALLET_SIGNER_MISMATCH. Body { label }: letters, digits, space, '.', '_' or '-' (max 64); null or empty clears it. Non-unique by design — display metadata only, the address remains the identity.
