fn admin(env: soroban_sdk::Env) -> Resultfn balance(env: soroban_sdk::Env, token: soroban_sdk::Address) -> i128ModERC3156 callback (used by Blend Protocol v2). Called with: exec_op(caller=from/G-address, token, amount, fee=0)
Blend has already transferred amount tokens to this contract.
After exec_op returns, Blend pulls repayment from caller (from)
via transfer_from. So we must transfer the borrowed amount back
to caller before returning.
