fix(onboarding): center step connector line & refresh welcome layout (#640)

* fix(onboarding): center step connector line with circles

The connector line was vertically centered against the circle+label
column, landing below the circle's center. Absolutely position the
label below the circle so the row height equals just the circle and
items-center aligns the line to the circle's center.

* feat(onboarding): refresh welcome layout & indicator spacing

- Place logo inline to the right of the Welcome heading
- Move the tagline badge below the heading with more breathing room
- Add space between the step indicator and step content
