Bring onboarding typography onto the unified scale

The first-run flow still carried its own sizes: a 34px hero, 13/12.5px
intros and helper text, 13px control icons. Restrain the hero to the 24px
display step and move intros/errors to 14px, helper text to 13px, and the
provider/workspace icons to the 16–18px standard. Structure was already
clean (two-pane, single cards) — this is purely scale alignment.
