zeus reviewed just now PR #1842, a3f9c21, retry refunds after a provider timeout

⚡ Do not merge this pull request yet.

The retry can create a second refund.

apps/api/src/refunds.ts:142

The payment provider creates the refund, but its response times out. The retry starts without checking the saved refund ID.

Test: Zeus forced the response to time out after the first refund. It then ran the retry.

Zeus reproduced the problem in the sandbox.

$ npx tsx .zeus/probe-refund-retry.ts refund re_84h2 issued 201 provider timeout — retrying refund re_91m7 issued 201 FAIL expected 1 refund, found 2
