Closes
[coder/internal#477](https://github.com/coder/internal/issues/477)

I'm solving this issue in two parts:
1. Updated the postgres function so that it doesn't omit 0 values in the
error
2. Created a new query to fetch the number of resources associated with
an organization and using that information to provider a cleaner error
message to the frontend
> **_NOTE:_** SQL is not my strong suit, and the code was created with
the help of AI. So I'd take extra time looking over what I wrote there
