Hotjar Analytics Integration Available Per Domain

Added Hotjar support to AI Commerce (frontend, backend, and admin domain settings). Merchants can install it per domain by inserting their domain-specific Hotjar Site ID into domains.hotjar_pixel. Once enabled on storefront, Hotjar records consent-gated heatmaps, click/scroll behavior, and session replays to reveal UX friction and conversion blockers. This helps merchants improve navigation, product discovery, and checkout usability faster, validate optimization ideas with real user behavior, and increase conversion with less guesswork.
