tec_matomo v1.2.0

Fixed

• Cart update tracking now clears the Matomo ecommerce cart before rebuilding it, preventing stale cart items from polluting product average price reports.
• Cart update tracking now uses the same no-combination SKU suffix convention as order tracking (idv0) and prefers unit prices over line totals.
• Order confirmation tracking now uses the canonical displayOrderConfirmation hook used by PS 1.7+ confirmation and free-order flows, and clears the Matomo ecommerce cart before sending order items.
• Order item prices now prefer the order line unit price including tax, matching product view tracking more closely.
