feat: expand confirm-tx warnings for contracts, burn addrs, scam list

- Expand scam address list from 7 to 652 addresses using MEW darklist
- Add contract address warning when sending directly to a smart contract
- Add null/burn address warning (0x0000...0000, 0xdead, etc.)
- All warnings use visibility:hidden/visible pattern (no layout shift)
- Scam and burn address checks are synchronous; contract check is async

closes #114
