One-time setup. Records the admin and the pool's SAC token, then unpauses.

Auth: requires the funder's signature; the same authorization covers the
inner SAC transfer(funder -> contract). Anyone may top up the pool.
fn fund(

on-chain receipt under grant_ref.
Auth: the contract admin only. A grant can be disbursed exactly once.
