chore: push card footer to bottom

[im-adithya]

Note

mb-5 is just added to keep the sats in other cards in the same line as Savings Balance sats, if this feels hacky, we can group Header and Content in a div and add flex flex-col justify-between to the <Card>

Before

After

justify-between seems better to me rather than random margins!

Done!

This adds quite a bit of markup :thinking: Couldn't you just add flex flex-col to the card and apply flex-grow to the CardContent element? That should work without additional markup...
