Multi-Wallet Approval Sweep

Sweeps Approval and ApprovalForAll logs across a whole list of wallets, then confirms each against current state so only approvals that still stand are shown. Results are grouped by spender rather than by wallet, which is the point: one spender holding rights over five of your addresses is a single point of failure that a per-wallet scan can never reveal, and revoking on one wallet leaves the rest exposed. Wallets are swept one at a time rather than concurrently, because several chunked log queries in flight is exactly what makes a public endpoint start refusing requests — and a refusal here reads as "no approvals", the most dangerous wrong answer this tool could give. Each revoke must be signed by the wallet that granted it, and the app refuses to send from the wrong account rather than producing a transaction that succeeds and revokes nothing.
