Improve Fourier labels and VeLa model naming

Include source series in Fourier-derived model descriptions and trim model labels before appending obs/time metadata to remove spacing artifacts. Default the VeLa model name (used in model descriptions when no file is loaded) from "Untitled" to "VeLa model".
