fix(fdt): Improve reporting of errors related to FDT setup

Change the doc comment (which also affects the implementation of `std::fmt::Display`) for `ConfigurationError::SetupFDT` to include the underlying `fdt::FtdError`. This improves both the reporting of failures during FDT setup on the logs, as well as the message in API server's corresponding HTTP response.
