With debug mode on, debugFetch logged every request's full URL and body,
so an RPC endpoint with an API key in its path or query string printed
that key to the console on every request. It now logs the HTTP method,
the URL's origin and, for a JSON-RPC body, the method name. The balance
refresh and token lookup, which logged the RPC URL at debug level, log
its origin too. The error lines for failed RPC calls print ethers' short
message, since its full message for an HTTP error carries the request
URL. The README's DEBUG Mode Policy says what debug mode logs.
Model: opus-5-5
Expands the confirm-tx warning system with three new warning types, all using the existing `visibility:hidden/visible` pattern from PR #98 (no animations, no layout shift).
## Changes
1. **Scam address list expanded** (7 → 652 addresses): Sourced from [MyEtherWallet/ethereum-lists](https://github.com/MyEtherWallet/ethereum-lists) darklist (MIT license). Checked synchronously before sending.
2. **Contract address warning**: When the recipient is a smart contract (detected via `getCode`), shows a warning that sending directly to a contract may result in permanent loss of funds.
3. **Null/burn address warning**: Detects known burn addresses (`0x0000...0000`, `0x...dead`, `0x...deadbeef`) and warns that funds are permanently destroyed.
4. **No-history warning** (existing from #98): Unchanged, still shows for EOAs with zero transaction history.
All warnings use reserved-space `visibility:hidden/visible` elements — no layout shift, no animations.
