day 15: added click tracking + share counter to heyou.page

quiet weekend, shipped analytics.

users now see on their dashboard:

• total page views

• times shared (qr + copy)

• per-link clicks

no fluff. just numbers.

how it works:

• edge middleware → log view

• supabase edge function → +1 on share

• link click → /api/click → +1
