fix: make success-tx addresses clickable, fix USDT ETH bug, nest decoded details (closes #80)

- Add underline + click-to-copy (data-copy) to addresses in toAddressHtml()
  so they match the style used everywhere else in the extension
- Fix 'USDT ETH' display: add rawValue to Uniswap decoder Amount details
  and extract Token In info for proper symbol resolution in approval.js
- Hide redundant top-level Amount/To when decoded details are present
  (they already show the same info inside the decoded section)
- Wrap decoded calldata details in a bordered well for visual separation
