fn admin(env: soroban_sdk::Env) -> soroban_sdk::AddressAggregate multiple contract calls in a single tx, taking affiliate fees up front.
Auth model: the user signs the outer tx as the source account. Soroban's
source-account auth covers user.require_auth() calls in any sub-frame
rooted at this tx, so targets like Aquarius can do user.require_auth()
token.transfer(user, …) without the router holding or approving funds.
The router never custodies user funds — it only orchestrates and bills fees.fn execute(
