When moving a schematic component whose pins directly touch pins of
stationary components (no wire segment, just pin-to-pin contact),
synthesize bridge wires to preserve the electrical connection after
the move. Also fixes duplicate-pin-position collision in old_to_new
map and updates symbol reference assignment to use setAllReferences.

When moving a schematic component, connected wires are stretched/shifted
to follow the component (like KiCAD's drag behaviour), preserving
connectivity instead of leaving dangling wire stubs.
Also fixes property labels (value, reference, etc.) so they shift with
the symbol rather than staying at their original positions.
