Stats: fix dashboard header/tab alignment

[myhro]

Closes Automattic/red-team#256.

Proposed Changes

Fix the alignment of the header and navigation tabs in the Stats dashboard on Calypso Blue.

Why are these changes being made?

These changes are being implemented to align the header and navigation tabs with the similar design found in the WP Admin dashboard.

Testing Instructions

• In a local or Calypso live environment, navigate to the Stats section in the sidebar of a given site.
  • This can also be tested using a Jurassic Ninja site, such as /stats/day/artistic-ukulele-worm.jurassic.ninja.
• Check the alignment of the Traffic / Insights / Subscribers navigation bar compared to the Jetpack Stats header.

Note

The length of the underline highlighting the active tab has been shortened slightly. This adjustment reflects the fact that the first item is no longer centered in its column. However, this behavior is consistent with what is observed in WP Admin:

Looks good to me. Tested on different resolutions and all seems good.

As mentioned in the ticket, it looks similar to wp-admin.

Thanks for the review, @Initsogar!

I'm holding on merging/deploying, as @kangzj might want to test it further.

Thanks @myhro for the fix. Happy for it to ship, but it'll be even better if you could take a look at the margin of the Jetpack log0 for screen width < 600px for Odyssey Stats. Thanks again for the fix.

@kangzj I've pushed a fix for the header alignment in Odyssey Stats. Can you please take a look again?
