CalibPressureAdvancePattern::line_width_first_layer() returned the raw initial_layer_line_width, so a value of 0 (which means "use the default") fed 0 into the Flow spacing math and threw FlowErrorNegativeSpacing, crashing the whole app when slicing a PA pattern calibration. Mirror the guard already present in the sibling line_width(): when the configured width is non-positive, fall back to auto_extrusion_width. Add a libslic3r regression test covering the width resolution. Fixes #13188
