🪲 saving programs consistently

Fixes #5507

Hi! I've been testing and, yes now the programs seem to be being saved more consistently. This is how a saved program from this page looks in the database:

    {
      "session": "fac24066d19f4fd8ac44508ac4a7fdae",
      "date": 1715266264375,
      "lang": "en",
      "version": "DEV",
      "level": 17,
      "code": "print 'hello' 1 + 2",
      "name": "Tik Tak Toe",
      "username": "teacher1",
      "error": false,
      "adventure_name": "Tik Tak Toe",
      "id": "720bcbb290384d7b9f5a018d168c8707",
      "username_level": "teacher1-17",
      "is_modified": true
    }

But I wonder if this is the solution? I think perhaps the best way is to not store programs in this page? I think we should only be storing programs that come from the /hedy page.
