Shape polar duplicate: show permanent sketch nodes in inspection and polar-duplicate modes

[trailcode]

Permanent "+" markers for user-placed sketch nodes (added via the Add Node tool) are now visible whenever a sketch is active in inspection mode or during Shape polar duplicate (which relies on sketch node snapping for the polar arm).

Previously, these nodes were only shown while actively using the Add Node tool (Sketch_add_node); they were hidden in Sketch_inspection_mode and Shape_polar_duplicate.

Changed the visibility condition in sync_permanent_node_annos_() from an explicit mode check to is_sketch_mode(mode) || mode == Mode::Shape_polar_duplicate.

Test plan

• Build in Release.
• Verify permanent sketch nodes ("+") are visible in Sketch inspection mode.
• Verify nodes visible during Shape polar duplicate for snapping the polar arm.
• No regression in other sketch tools or when leaving sketch modes.
