GET /api/referral/me only ever reports a user's own referral stats — this is the admin-wide view: referral-driven signups over time, top referrers, and (since migration 035) a channel breakdown across referral links, UTM campaigns, and organic/direct signups.
Every signup in the window, bucketed by UTM source when present, else "referral (no UTM)" or "organic / direct".
Who's actually driving signups, this window.
