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
- Add deleted column to organizations table
- Add trigger to check for existing workspaces, templates, groups and
members in a org before allowing the soft delete

The first organization created is now marked as "default". This is
to allow "single org" behavior as we move to a multi org codebase.
It is intentional that the user cannot change the default org at this
stage. Only 1 default org can exist, and it is always the first org.
