updates, with no impact to card flows, navigation, or data handling.
> 
> **Overview**
> Updates `CardHome` to render its main call-to-action buttons (`Add
funds`, `Enable card`, `Change asset`, and the error `Try again`) using
`ButtonVariants.Primary` instead of `Secondary`, changing their visual
styling.
> 
> Regenerates `CardHome` Jest snapshots to reflect the new button colors
(e.g., dark background and white label text).
