fix: handle empty org list gracefully during login

SelectOrganization() returns (nil, nil) when the org list is empty.
Both `depot login` and `depot org switch` dereferenced the nil pointer,
causing a panic.

Now login completes successfully (token is saved) and prints a helpful
message when no orgs are found. org switch returns a clear error.
