Add identity context and ASP.NET individual account pages for authorization.

I created a new Blazor project with individual accounts, then transferred the files over to the existing project.
Then renamed ApplicationDbContext to: IdentityContext to distinguish from the application context.
Then ran the update database command with the existing migration for identity.
