feat: move_schematic_component with wire preservation (drag behavior)

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.
