Slice 1 of discussion #503 (from-to wiring list built on projectDataBase).
Conductor is the one item type on a diagram without a stable identity
of its own -- Element and Diagram both have a uuid, Conductor didn't.
This is the prerequisite the wiring-list tables need: a conductor
table keyed by uuid, the same way the existing element table is keyed
by Element::uuid().
- Conductor gets a QUuid m_uuid, generated in the constructor, with
uuid()/newUuid() accessors mirroring Element's exact pattern.
- toXml()/fromXml() read/write a "uuid" attribute the same way
Element already does, including the same generate-on-missing
fallback (QUuid(e.attribute("uuid", QUuid::createUuid().toString())))
for projects saved before this change.
- PasteDiagramCommand::redo() calls newUuid() on every pasted
conductor (content.conductors(), all three categories), mirroring
the existing per-element newUuid() call right above it -- otherwise
copy-paste would duplicate a conductor's uuid.
Backward compatibility: Conductor::valideXml() doesn't require the
"uuid" attribute, so old files parse unchanged. Verified by opening a
genuinely pre-uuid project (examples/industrial.qet, 150 folios, 671
conductors, legacy integer terminal1/terminal2 references with no
uuid attribute at all) -- loads and renders correctly, gets uuids
assigned on load, and those uuids are stable across a second
load/save cycle (byte-identical uuid values). Verified paste
separately: copying a selection with conductors and pasting produces
distinct new uuids for every pasted conductor, none colliding with
the originals or each other.
Fix : in old projects without the conductors formula, the conductors texts aren't loaded and displayed
Fix it in method void Conductor::refreshText()

The change is apply for every conductors in the same potential

Use method toXml and fromXml of sequentialNumbers.
Use m_freeze_label instead of m_frozen_label to save the frozen status of the text item.

Element now use methods (toXml and fromXml) of sequentialNumbers to store and load sequential.
