Adjust recent cards animation.

= Make the card clip more gradual (half that of before).
= Accelerate the opacity fade so the content does not intersect with
the card bounds when clipping.
= Shift the search text 2dp to the left to better align with the
recent card content.
= Adjust the y translation of the recent card to "center" vertically.
