Note

Low Risk
Low risk: primarily copy/translation key updates plus minor UI tooltip/toast rendering changes (adds a terms link and an extra success-toast description) with no changes to conversion logic or data handling.

Overview
Updates mUSD conversion user-facing messaging to consistently describe the incentive as an annualized bonus and to communicate that the bonus becomes claimable within about a day.

This refreshes strings across the education screen, quick convert header, asset overview CTA, claimable bonus tooltip, and conversion success toast (now includes a secondary description line), and adjusts the confirmation PercentageRow tooltip to include a tappable “Terms apply” link to the bonus terms URL. Tests are updated to match the new copy and label formatting.

E2E Test Selection:
The changes are primarily copy/text updates and minor UI enhancements to the mUSD conversion feature:

1. Localization changes (en.json): Updated tooltip text, changed "receive up to a X% bonus" to "earn up to a X% annualized bonus", added new toast description, renamed parameter from apy to percentage

2. MusdQuickConvertView: Simple parameter rename from apy to percentage in string interpolation

3. useEarnToasts.tsx: Added a secondary description text to the success toast for mUSD conversion delivery

4. percentage-row.tsx: Added a clickable "Terms apply" link in the tooltip that opens the bonus terms of use URL

The mUSD conversion E2E tests are tagged with SmokeWalletPlatform (tests/smoke/wallet/musd-conversion-happy-path.spec.ts). While there are also mUSD-related tests in SmokeTrade (gasless swap) and SmokeRamps (sell mUSD deeplink), those tests don't directly exercise the changed components (toast messages, tooltip content, or the quick convert view copy).

The changes are low risk because:

• They are primarily text/copy changes
• The toast enhancement adds a secondary description without changing existing behavior
• The tooltip link addition is a minor UI enhancement
• All unit tests have been updated to match the new behavior

SmokeWalletPlatform is sufficient to validate the mUSD conversion flow which exercises the changed components.

Performance Test Selection:
The changes are purely copy/text updates and minor UI enhancements (adding a secondary toast description and a clickable link in a tooltip). These changes do not affect rendering performance, data loading, state management, or any critical user flows that would impact app performance. No performance tests are needed.
