routes: layout: Adjust field with new API

A bit breaking change, all user info is now stored at "user_info" field.

Before:
```
{
  "code": 200,
  "res": {
    "id": 2,
    "full_name": "Ammar Faizi",
    "gender": "m",
    "username": "ammarfaizi2",
    "role": "user",
    "is_active": "1",
    "renew_token": {
      "token": "...",
      "token_exp_at": 1741842452
    }
  }
}
```

After:
```
{
  "code": 200,
  "res": {
    "user_info": {
      "id": 2,
      "full_name": "Ammar Faizi",
      "gender": "m",
      "username": "ammarfaizi2",
      "ext_email": "[email protected]",
      "role": "user",
      "is_active": "1",
      "socials": {
        "github_username": "ammarfaizi2",
        "telegram_username": "ammarfaizi2",
        "twitter_username": "ammarfaizi2",
        "discord_username": "ammarfaizi2"
      },
      "photo": null
    },
    "renew_token": {
      "token": "...",
      "token_exp_at": 1741842452
    }
  }
}
```
