fix: consistent token contract display on confirm-tx page

The confirm-tx page displayed token contract addresses as plain text,
while addressToken used a styled container (bg-hover rounded-md) with
color dot, copy-on-click, etherscan link, and token metadata.

Changes:
- confirm-tx HTML: use bg-hover rounded-md container matching addressToken
- confirm-tx JS: render contract with addressDotHtml, copy-on-click span,
  etherscan link, and optional token name/symbol metadata
- send.js: pass tokenName to confirmTx for richer contract display
- Add click-to-copy handler for contract address on confirm-tx

Closes #70
