fixup: use validated str from validate_resource_name; also validate range

- drive: use the &str returned by validate_resource_name(parent)? directly
  in json! rather than the original untrusted input
- sheets: validate config.range in both build_append_request and
  build_read_request, since the range is used as a URL path segment in the
  Sheets API (spreadsheets/{id}/values/{range})
