feat(product): add reusable Product Experience 2.0

Unify product details modules behind config-driven contracts so teams can
extend UX without changing runtime architecture or bootstrap flow.

Keep backward compatibility with existing product payloads by treating new
media/specification/variant/related structures as optional extensions.

Improve conversion and content discoverability with reusable actions,
typed media rendering, grouped specifications, dynamic variants, and
multi-collection related products.
