Subject: [PATCH 1/3] fix(GRO-876): wire up refund button in invoice detail
 modal

Cherry-pick of 628ed34 to fix @typescript-eslint/no-unused-vars
error on PR #351 Lint & Typecheck.

The issueRefund function was defined but never called. This commit:
- Removes the inline async onClick handler that bypassed issueRefund
- Wires the Refund button to open setShowRefundDialog(true) instead
- Uses issueRefund function (with refundAmount/refundError/refunding state)
- Adds manager role check before showing refund button
- Shows "Refunded" badge when invoice.stripeRefundId is set

Subject: [PATCH 2/3] fix(GRO-876): remove dead issueRefund function from
 InvoiceDetailModal

The inline async onClick handler already calls the refund API directly. The
separate issueRefund function was defined but never called, causing
@typescript-eslint/no-unused-vars CI failure on PR #351.
