Log NetUP request/response body; fix reservation_id to be numeric

- reservation_id converted to integer (NetUP likely requires number not UUID string)
- Log requestBody sent to NetUP and responseBody received from NetUP
- Push event rows now expandable: click to see URL, request JSON, NetUP error response
- Same for checkout
