Track all link clicks (internal + external) in analytics; v1.1.33

Replaces outbound-only tracking with a useLinkClickTracking hook that
captures every <a> click on the site. Stores as link_click events keyed
by destination URL, with an internal flag. Admin analytics page gains a
Link Clicks table sorted by count, showing type (internal/external).
