Summary

Fixes CMS values that read a field from an enclosing collection inside a nested collection (bound via collection_layer_id) rendering empty on published/preview pages while working correctly on canvas. Surfaced on a client app where region "badges" inside a multi-reference collection were blank in preview.

Changes

• Re-attribute bindings carrying an explicit collection_layer_id to that ancestor collection layer's bound-path set, so the ancestor item's reference paths get expanded during SSR
• Load relationship target fields even when the referenced collection is also a primary (scanned) collection, so the target value is present in the cache

Test plan

• Open a published/preview page with a nested collection whose child reads a field from the parent collection via a relationship (e.g. badge showing Region → Name)
• Confirm the value renders (previously blank) and matches the canvas
• Verify normal (non-nested) collection bindings still resolve
• Verify reference fields targeting a non-primary collection still resolve
