Fix Identity scaffolding.

[bitbound]

I still have some cleanup/fixing to do in regard to DB providers and migrations.

First thing is that I'm unable to self-delete an account via Identity UI because the UserManager class isn't doing cascade deletes on related tables.

I needed to import the DeletePersonalData page from the Identity UI and override it to use the DataService class instead.

However, the Identity scaffolding was failing because it wasn't recognizing the classes for Razor components that didn't have a code-behind partial class. These components are basically like Vue's SFC. After explicitly creating a partial class in CS, I was able to import the page and make the change.

It looks like a lot of changes, but it isn't really.

• Commit 1: The majority of this is moving C# code from Razor components to partial classes in CS files.
  • I also updated NuGet packages and added detailed EF logging in dev environment.
  • Everything under the /Areas/Identity was auto-generated by scaffolding.
• Commit 2: This was almost all done by the Identity scaffolding. The only thing I did was replaced UserManager with DataService when deleting the user.
• Commit 3: Just updated the submodule.
