Build Queries for Admin Comments

Implementation description

• Adds getAdminCommentsByApplicantRecordId and getAdminCommentById queries to services
• Adds corresponding resolvers and types
• Ensures queries are protected by authorizedByAdmin middleware

Steps to test

1. Run the following queries and ensure proper responses:

# Fetch all comments for an applicant record
query {
  adminCommentsByApplicantRecordId(applicantRecordId: "aa6cb234-ecc5-43e5-b2cf-4ec426577658") {
    id
    userId
    applicantRecordId
    comment
    createdAt
    updatedAt
  }
}

# Example of expected response
{
  "data": {
    "adminCommentsByApplicantRecordId": [
      {
        "id": "some-comment-id",
        "userId": 1,
        "applicantRecordId": "aa6cb234-ecc5-43e5-b2cf-4ec426577658",
        "comment": "Test admin comment",
        "createdAt": "2025-10-25T20:50:57.520Z",
        "updatedAt": "2025-10-25T20:50:57.578Z"
      },
      ...
    ]
  }
}

# Fetch a single comment by ID
query {
  adminCommentById(id: "some-comment-id-from-previous-query") {
    id
    userId
    applicantRecordId
    comment
    createdAt
    updatedAt
  }
}

# Example of expected response
{
  "data": {
    "adminCommentById": {
      "id": "some-comment-id-from-previous-query",
      "userId": 1,
      "applicantRecordId": "aa6cb234-ecc5-43e5-b2cf-4ec426577658",
      "comment": "Test admin comment",
      "createdAt": "2025-10-25T20:50:57.520Z",
      "updatedAt": "2025-10-25T20:50:57.578Z"
    }
  }
}

What should reviewers focus on?

• Just make sure the 2 queries run as expected
