fix(custom-fields) : include orphan values with embedded definitions in edit pages

After JSON-to-tables migration, custom field definitions not linked to
a ModelType were invisible on edit pages because buildCustomFieldInputs
only mapped over structure definitions. Now also includes values whose
embedded customField definition has no matching structure entry.
