Original task (Task #35): When the admin dashboard's custom range receives a malformed or missing date (e.g. ?range=custom&from=foo), the API silently fell back to the 7-day window instead of returning an error. This masked client bugs and confused admins. Changes: - artifacts/api-server/src/routes/stats.ts: - Refactored the custom-range branch so range=custom now always validates from/to. Returns 400 with a helpful, specific message when: * from or to is missing * from or to is not a valid YYYY-MM-DD UTC date * from is after to (existing behavior, message clarified) - Removed the silent `if (range === "custom") range = "7d"` fallback. - lib/api-spec/openapi.yaml: - Documented the 400 ErrorResponse on getAdminStats so the generated clients know about this failure mode. - Regenerated @workspace/api-client-react and @workspace/api-zod via `pnpm --filter @workspace/api-spec run codegen`. - artifacts/teaboy-os/src/pages/admin.tsx: - Captured `error` from useGetAdminStats (with retry: false) and surface a translated, role="alert" panel beneath the range controls when the API returns an error, including the server's error message. The frontend already guards against client-side invalid input via isCustomValid, so this primarily covers any remaining edge cases (stale querystring, race conditions). - Added admin.dashboard.customRange.loadError translations in en.json and ar.json. Verified with `pnpm -w run typecheck` (passes for libs and all artifacts). Manual curl confirmed the route is wired (auth gate returns 401 first, as expected).
