pub async fn cancel_all_orders(
__arg0: State<AppState>,
) -> Result<SonicJson<ApiResponse<CancelAllOrdersResponse>>, ApiError>Expand description
Cancel all market-maker orders across all wallets (testnet only)
Cleans up orphan orders left by previous MM instances that used
ephemeral wallets. Only available when modes.enable_test_endpoints=true.
Identifies MM orders by client_id matching the cli_\d+ pattern
(from wallet_client.rs: format!("cli_{}", nonce)). User orders
placed via the frontend are left untouched.
