Admin Traffic tab: referring domains, landing pages, angles, by day

traffic.js logs public page views by referring domain (30 s buffered; page_hits
table or traffic.json), coach exposes all join-page views, and
/api/admin/traffic merges page views, join-page views, signups, registrations
and $20+ buyers by first-touch source for 7/30/90/365-day ranges.
Also: line-tree chips no longer truncate own-position labels.
