Objective

Reseller providers were being created without a value for the Name column, just a value in the BusinessName column.
This PR addresses this by adding a new field to the Reseller creation form and by populating existing Providers Name column with the value from the BusinessName column.

Code changes

• src/Admin/Models/CreateProviderModel.cs: Added a field for the Name column
• src/Admin/Views/Providers/Create.cshtml: Added a field for the Name column
• util/Migrator/DbScripts/2023-08-03_00_PopulateResellerNames.sql: SQL migration script to populate the Name column for existing entries with a NULL value

Before you submit

• Please check for formatting errors (dotnet format --verify-no-changes) (required)
• If making database changes - make sure you also update Entity Framework queries and/or migrations
• Please add unit tests where it makes sense to do so (encouraged but not required)
• If this change requires a documentation update - notify the documentation team
• If this change has particular deployment requirements - notify the DevOps team

This should be in the DbScripts_data_migration folder because it is data migration only. And you need to coordinate with devops so they know to run it.

As discussed, providers are not supported on self-hosted, so EF migrations are not required.
