Add English translations (qet_en.ts) for the new conductor-panel strings
so non-French users don't see untranslated source text: the panel title,
the two undo captions, the apply-to-all checkbox, and the View-menu
toggle + status tip.
The apply-to-all checkbox now reuses the modal dialog's exact wording
("Appliquer les propriétés a l'ensemble des conducteurs de ce potentiel")
for consistency and so it shares the existing translation.

Port the modal dialog's "apply to all conductors" option into the dock
panel, resolving the open propagation question. A persisted checkbox,
pinned above the tabs, makes each edit propagate to every conductor on
the same potential in one undo step - identical semantics to
ConductorPropertiesDialog, but the choice is remembered across edits.

Addresses the testing feedback on the conductor selection-properties
prototype:
1. Edits were never applied. The dock drives every editor through
setLiveEdit(true), which each editor overrides to connect its field
changes to apply(); ConductorPropertiesEditorWidget didn't override it,
so the call was a no-op. Implement setLiveEdit() to connect the hosted
ConductorPropertiesWidget's controls (commit-style signals) to apply().
A m_updating guard suppresses the signals emitted while the widget is
loaded programmatically, so a partial mid-load state is never committed.
2. Clicking a conductor's text label showed nothing, because the label is
a ConductorTextItem, not a Conductor. Map it to its parentConductor() in
the editor factory, mirroring the double-click-the-label dialog behaviour.
3. The panel sat at a small size hint with empty space below it. Give the
editor an Expanding vertical size policy (and a minimum height) so it
fills the dock like the other editors.
