ElementsPanelWidget::duplicateDiagram() round-trips the folio through XML and then gives the copied *elements* fresh uuids, because element.uuid is the primary key of the project database and a duplicate silently fails to insert. Conductors now have the same problem and needed the same loop: conductor.uuid is likewise a primary key, its insert is a plain INSERT rather than INSERT OR IGNORE, and a failure only reaches qDebug(). Without this, every wire on a duplicated folio is missing from the wiring list and from the per-element wire count, with nothing shown to the user. Verified against the real schema: inserting the same conductor uuid for a second folio fails with "UNIQUE constraint failed: conductor.uuid", leaving one row where two were expected. Also harden the uuid read in Conductor::fromXml(). The default argument of QDomElement::attribute() is evaluated whether or not the attribute exists, so a uuid was minted for every conductor on every load and thrown away; and the default only applies when the attribute is *absent*, so a present but empty or malformed uuid="" parsed to a null QUuid rather than a fresh one -- and null uuids collide with each other exactly as duplicates do.
