Subject: [PATCH] fix: show decoded swap details on success-tx view (closes
 #63)

Carry decoded calldata info (action name, description, token details,
amounts, addresses) from the approval confirmation view through to the
success-tx view. For swap transactions, this now shows the same decoded
details (protocol, action, token symbols, amounts) that appeared on the
signing confirmation screen.

Changes:
- approval.js: store decoded calldata in pendingTxDetails.decoded
- txStatus.js: carry decoded through state.viewData, render in success view
- index.html: add success-tx-decoded container element
