Add manual conductor routing to the scripting API

Browse Source 
Conductor::moveSegment(index, dx, dy) is the same primitive
handlerMouseMoveEvent()/handlerMouseReleaseEvent() apply on a drag --
move both axes on the target segment (each of ConductorSegment's
moveX()/moveY() silently no-ops on the wrong axis or a static,
terminal-anchored segment), recompute the path, and push one
ChangeConductorCommand undo step via the existing saveProfile().

Caught while writing the first test for it: moveSegment() never set
modified_path, so Conductor::toXml() skipped writing <segment> children
and a manually rerouted conductor silently reverted to auto-routing on
the very next save -- the change took effect in the running scene but
never reached disk. Fixed by setting the flag, the same as every other
path-modifying call site already does.

qet.conductorSegments() lists a conductor's segments (endpoints in
scene coordinates, orientation, static/movable) so a script can find
the index it wants; qet.moveConductorSegment() applies the move and
refuses a static segment or an out-of-range index.

Move one segment of this conductor by (dx, dy), the same primitive

drag -- moveX()/moveY() each silently no-op on the wrong axis or a
static (terminal-anchored) segment, so both are always called and
whichever applies takes effect. Unlike a drag this commits the whole
move as a single undo step.
