jaeone94 2e4c9c6fdc style: use neutral credits info button (#13461) ...

## Summary

Replaces the Additional credits tooltip trigger with the shared Button
component so the icon renders with the neutral muted treatment used by
the rest of the UI.

## Changes

- **What**: Uses the shared Button component for the Additional credits
info action while preserving the existing tooltip and aria label.
- **Dependencies**: None.

## Review Focus

Confirm this remains a visual-only change scoped to the Plan & Credits
credits tile.
