Add linked account details when fetching in app wallet user details

Previously, when querying for user details via the in app wallet backend API, you would get something like:

[
  {
    "userId": "2c7af0c5-798d-446a-9a30-305110c57783",
    "walletAddress": "0x9020d2941ad941ABc1C2890301D8F889e263b0C4",
    "phone": "+1234567890",
    "createdAt": "2024-04-03T16:36:26.379156+00:00",
  }
]

Now it returns something like:

[
  {
    "userId": "2c7af0c5-798d-446a-9a30-305110c57783",
    "walletAddress": "0x9020d2941ad941ABc1C2890301D8F889e263b0C4",
    "phone": "+1234567890",
    "createdAt": "2024-04-03T16:36:26.379156+00:00",
    "linkedAccounts": [
      {
        "type": "cognito",
        "details": {
          "phone": "+12265055474"
        }
      }
    ]
  }
]

Note the addition of the linkedAccounts field.

This adds full support for linked accounts which we introduce a while back.
