survey_responses accepting new format

[ezhang61]

The previous data structure is like:
{
"isComplete": true,
"responses": {
"ChildSurveyIntro": null,
"ClassFriends": "0",
"ClassHelp": null,
...
}
} And now it's been changed to {
"isComplete": true,
"responses": {
"ChildSurveyIntro": null,
"ClassFriends": {
"responseTime": {
"time": "2025-07-02T15:19:45.303Z"
},
"responseValue": "3"
},
"ClassHelp": {
"responseTime": {
"time": "2025-07-02T15:19:55.101Z"
},
"responseValue": "3"
},
"ClassNice": {
"responseTime": {
"time": "2025-07-02T15:20:10.472Z"
},
"responseValue": "2"
}, and that's why we are having responseTime and responseValue showing up in the response.
