Advertisers/admins had no way to see how many times an ad was actually
shown — only engagement counts (reactions/comments/reposts) existed.
Adds Advertisement.adViewCount, a denormalized counter matching the
existing engagement-counter pattern.
AdCard.tsx fires ads.recordView once per card, the first time it
scrolls ≥50% into view (react-intersection-observer's triggerOnce,
already a project dependency via FeedList's pagination sentinel) —
matches standard "viewable impression" semantics rather than counting
on mount (which would also count ads that render off-screen and are
never actually seen). Not deduplicated per pet, unlike reactions/reposts
— an impression counts every time an ad becomes visible, matching how
ad platforms report view counts.
Admin ads panel (/p/[secret]/ads) now shows view/reaction/comment/
repost counts inline on every ad row — the actual "results" advertisers
want from a placement, previously not surfaced anywhere despite already
existing on the Advertisement row for the other three counters.
