The etherscanLinkHtml helper had added border, px-1, hover:bg-fg,
hover:text-bg, and cursor-pointer classes that no other view uses.
All other views (addressDetail, addressToken, confirmTx, send, receive,
home, txStatus) use only 'inline-flex items-center' on etherscan links.
Removed the extra classes for consistency.
- Preserve contract call metadata (direction, label, method) when token
transfers merge with normal txs in fetchRecentTransactions
- Handle 'contract' direction in counterparty display for home and
address detail list views
- Add decoded calldata display to transaction detail view, fetching
raw input from Blockscout and using decodeCalldata from approval.js
- Show 'Unknown contract call' with raw hex for unrecognized calldata
- Export decodeCalldata from approval.js for reuse
