Extract the duplicated offline response payload and common headers into
constants to improve maintainability and readability.
- Define OFFLINE_RESPONSE for { status: "offline" }
- Define COMMON_OPTIONS for { headers: { "Cache-Control": "no-store" } }
- Use these constants across all response paths in the route.
