## Summary
feat(gateway): add request history lookups
## Test Plan
✅ `make fmt && make build && make test && make e2e-test`
### Local full-stack gRPC verification
- Date: `2026-07-15`
- Commit: `d814bd69c547418294ba684d49900264189a48fe`
- Started a clean local Gateway, Orchestrator, Runway, and MySQL stack
with `make local-submitqueue-start`.
- Called the real Gateway server with `grpcurl` using
`api/submitqueue/gateway/proto/gateway.proto`.
- Submitted the same pinned change twice. Request 1 landed; request 2
reached `error` as a duplicate of the in-flight request.
| Endpoint | Verified behavior |
|---|---|
| `GetRequestSummaryByID` | Returned the landed summary and an error
summary containing `lastError`. |
| `GetRequestSummaryByChangeURI` | Returned both matching summaries,
newest first. |
| `List` | Returned both queue receipts over two pages with `pageSize:
1`. |
| `GetRequestHistoryByID` | Returned chronological histories ending in
`landed` and `error`. |
| `GetRequestHistoryByChangeURI` | Returned both histories in ascending
sqid order and preserved terminal `lastError`. |
