Prepare a user-signed sendAsset transfer between users, subaccounts, spot and perp DEXs. Use "" for the default perp DEX and "spot" for spot; perp transfers require the collateral token. Sign with the main wallet and submit unchanged to send-asset/execute (unpaid). Invalid input returns 400; execution may return 422 for rejection or 502 for provider failure. Treat spot and perp as one balance only when the account abstraction mode is "unifiedAccount".
