CSV import/export mapping for product durability fields

[muratcakir]

Goal
Allow bulk maintenance via CSV/PIM.

Implementation

• Add CSV columns:

  • HasDurabilityGuarantee
  • DurabilityGuaranteeMonths
  • DurabilityGuaranteeIssuer
  • DurabilityGuaranteeTermsUrl

• Provide data validation on import:

  • If HasDurabilityGuarantee=true and months missing/invalid → import warning + set flag false (or fail row; pick and document)

• Document column semantics in admin import UI help.

Acceptance criteria

• Merchant can export, edit, and re-import durability data without losing values.
• Invalid data doesn’t silently create a broken label on storefront.
