fix: add top padding to sticky review block header (#1660)
* fix: add top padding to sticky review block header

The sticky per-block header on the reviews page had padding below but
none above, so the block number badge sat glued against the top edge
when pinned. Add matching top padding for breathing room.

* chore: use py-2 shorthand for review block header padding
