Transaction Details > Dispute Details: issuer evidence UI (Review the claim & View dispute details)

[Jinksi]

Part of #6883

This issue handles the features of Transaction Details → Dispute Details that require linking to a dispute's issuer_evidence if it exists:

1. The Steps to resolve → Review the claim row should be rendered with a link that opens the issuer evidence PDF in a new window.

2. The View dispute/inquiry details button should be rendered. When clicked, it will open the issuer evidence PDF in a new window – only for lost disputes that were:
   • Accepted (disputes.metadata.__closed_by_merchant)
   • Lost due to non-response (no dispute.metadata.__evidence_submitted_at)
   • Inquiry: Closed (dispute.status === 'warning_closed')

Note on testing issuer_evidence

Update: testing issuer_evidence (PDF of issuer claim) is not possible with test mode transactions. dispute.issuer_evidence will return null unless the dispute occurs on a live account with a real disputed transaction.

I've added an Issuer_Evidence TS interface to client/types/disputes.d.ts in PR https://github.com/Automattic/woocommerce-payments/pull/7047/files#diff-3281997a33f70ad0c3013fdb32857f43264b59ddf3b76dd1f3aef2d0b8b435edR35 – if it is useful when working on this issue.

This issue is on hold and may or may not be picked up later. A different iteration of this issue is being worked on in #7173.

This is a task from a previous project, which we didn't pursue (design iteration & testing challenges).

We have a future project to improve the UI for accessing & viewing dispute issuer evidence. Closing this issue, as we are not planning to handle as maintenance. If there is relevant info in this issue then we can review when we start work on the project.
