Improve digitizing cursor contrast and lock tools during tracking - #39

Conversation
Apply the same dual-layer shadow technique used by CalibrationToolNode and CoordinateSystemNode to the digitizing crosshair cursor. A dark shadow stroke (4 px) renders beneath the white cursor stroke (1.5 px), giving good contrast on both light and dark video backgrounds instead of relying on a single color that only works on one background type. Also prevent accidental interference with the calibration tool and coordinate system while a track is being manually digitized: both nodes dim to 35% opacity and become non-interactive (pickable: false) when activeTrackIdProperty is set, restoring to full opacity and interactivity once digitizing ends. https://claude.ai/code/session_01VAVzhrFTMNh4duuDe4v2uh
