[Bug][Enhancement] Login Partial, etc.

First though, In the dotnet build and dotnet run or dotnet watch run on linux or Windows with the proper SDK's installed and make sure to install the .NET 8 SDK. This should start Kestrel sever and load the localhost:5000 or 5001 to the browser. Yes this does work in Linux.

As for the issue, the Login and Register Partial doesn't work.

If you click on Login it navigates in the browser to `https://localhost:5001/Account/Login` but 404's.
If you click on Register it navigates in the browser to `https://localhost:5001/Account/Register` but also 404's
There's a _LoginPartial.cshtml in /Shared but I don't think it's actually being used. There is no Login /Views related to Login.
There's no _RestierPartial.cshtml in /Shared and no /Views related to Register

Create the Views and or partial and use them.

I feel like the Login and Register page could be one page, since they have similar fields, but if they are separate, that might work well as a modal,
