Stats: Sparkline is different between Calypso and WP Admin

[mmtr]

The stats sparkline rendered in Calypso does not fully match the one rendered in WP Admin:

Calypso	WP Admin

The one in Calypso is brighter, placed in a different position, and with a slightly different size.

This happens in both Simple and (as of Automattic/jetpack#21655) in Atomic sites.

Small note, WPcom_Admin_Menu::add_stats_menu and Atomic_Admin_Menu::add_stats_menu should also rely on the same implementation as much as possible.

Not sure we can do much more. Stats data is on WP.com, so it's directly available for Simple sites. However, Atomic and Jetpack sites need to perform a remote request to WP.com to fetch the data. That's why the current implementation is different.

Added this to our Iteration 3, but it's so minor that I'd just give this a quick investigation and only act if it's a quick win.

My hunch is that it'd be easier to make the Calypso version look like the wp-admin one, but it might be my front-end bias speaking.
