BUG E/F: the Vendor and Client wizard step cards overflowed — horizontal
scrollbar, clipped fields, a huge empty grey left region. The step-card lays the
step timeline in a vertical left sidebar (grow-0, self-stretch), but
vendor-timeline/client-timeline rendered the HORIZONTAL `timeline` component,
which forced the shrink-to-fit sidebar to ~full card width and pushed the body
off-screen.
- vendor-timeline / client-timeline: use timeline/vertical-timeline +
vertical-timeline-step (the components already existed) instead of the
horizontal pair.
- vendors.clj: step bodies w-[600px] h-[350px] -> w-full h-[350px] so the body
fills the width left of the now-narrow vertical timeline.
Verified live (agent-browser): Vendor 760x520, Client 820x560, vertical timeline,
no horizontal overflow, Info->Terms navigation + validation re-render lay out
correctly. Both files pass lein cljfmt check.
