Tech discovery - search customer by phone (Admin tool)

User Service API: Adapt GET user endpoint to also search by phone number
User Service API: Adapt the create method in user service to create a lookupByPhoneNumber record if a phone number is informed
User Service API: Adapt update-user lambda to update or create a lookupByPhoneNumber record if the phone number changed
User Service API: Add a isPhoneNumberVerified field to lookupByPhoneNumber interface. This is important to avoid impacting https://rbictg.atlassian.net/wiki/spaces/EGMT/pages/4329078785/Solution+Phone+Number+Authentication+for+BK+SA#Customer-support-tool
User packages: Change getByPhoneNumber to use User Service API instead of directly accessing the database
Admin App Backend: Create a GraphQL query to request customers by phone number
Admin App Frontend: Add the option to search customers by phone using the new query
DynamoDB: Develop a migration script to create lookupByPhoneNumber for existing customers

Search customer by phone sequence diagram:

export interface IUserLookupByPhone {
  pk: string;
  pk2: string;
  sk: string;
  sk2: string;
  isVerified: boolean;
}

Create lookupByPhoneNumber record after creating the user in dynamo inside the pre-signup lambda, but only if a phone number is informed: https://github.com/rbilabs/intl-user-service/blob/master/src/cognito-lambdas/pre-signup.service.ts#L135
Update the lookupByPhoneNumber record if an user update is triggered and includes the phone number: https://github.com/rbilabs/intl-user-service/blob/master/src/users/update-comm-pref.service.ts#L150
Adapt the get user endpoint to have an phoneNumber query field, that searches by phone: https://github.com/rbilabs/intl-user-service/blob/master/src/users/users.controller.ts#L124
Create a LaunchDarkly Flag and request it via a backend query (https://github.com/rbilabs/intl-admin-app/blob/master/src/remote/queries/launch-darkly.ts )

Create the option to search lookupByPhone records created by user-service using the endpoint. Currently, getByEmail already works this way (https://github.com/rbilabs/intl-packages/blob/master/packages/users/src/users.ts#L359).

~~This changes are already implemented in this git branch:~~ https://github.com/rbilabs/intl-packages/pull/961
