feat: reorganize transaction detail view layout

- Move transaction hash (txid) to first position after title
- Group fields into logical sections with visual dividers:
  Identity (hash, type, status, time), Value (amount, native qty,
  token contract), Parties (from, to), Protocol (calldata/action),
  On-chain (block, nonce, fee, gas price, gas used), Raw data
- Add tx-detail-group CSS class for subtle border separators
- Show on-chain details group wrapper only when data is loaded
- Maintain all existing functionality and copy-to-clipboard behavior
