Add component tests for components/streams/download-receipt-button.tsx

[Austinaminu2]

Description

`components/streams/download-receipt-button.tsx` has no test coverage for its disabled state, click handler, or the generated download's attributes/content.

Task

Small, self-contained component with a clear primary interaction (click → download) to verify.
