fix: inherit conductor line style (pen style) when linking cross-references

ApplyForEqualAttributes() was missing the 'style' attribute, causing
dashed/dash-dotted line styles to be lost when potentials are merged
via folio reports. Only color and other properties were copied.

Add style copy in single-element case and equality check in
multi-element case, matching the existing pattern for other attributes.
