fix: default-initialize WallToolPathsParams fields (#15138)

Browse Source 
min_length_factor and is_top_or_bottom_layer had no default initializers, and the FillConcentric/FillConcentricInternal callers never set them, so WallToolPaths::removeSmallLines() thresholded on stack garbage. Which short extrusion lines it dropped then depended on memory layout, so concentric solid-infill output was nondeterministic between runs and across machines. Give every member a default, matching the adjacent FillParams. The perimeter path was already fine because it builds the struct via make_paths_params().
