Show move length in Previewr panel (#15326)

Browse Source 
Adds a new "Length" row to the sequential marker position popup in GCodeViewer and updates row capacity accordingly.
For arc commands (G2/G3) that are split into multiple vertices, it now sums segment distances across vertices with the same gcode_id so the displayed value reflects the full move length instead of a single chord.
