* Port Pressure Advance visualization to libvgcode architecture

Adapt PA visualization (originally in commit e3a77259) to work with
the new libvgcode library introduced by upstream PR #10735.

Changes across the libvgcode stack:
- PathVertex: add pressure_advance field
- Types.hpp: add PressureAdvance to EViewType enum
- ViewerImpl: add ColorRange, color mapping, range updates for PA
- LibVGCodeWrapper: pass pressure_advance from MoveVertex to PathVertex

GCodeViewer UI integration:
- Add "Pressure Advance" to view type dropdown
- Add PA color range in legend (3 decimal places)
- Add PA value display in sequential view marker tooltip
- Add PA row in position properties table

The GCodeProcessor PA parsing (M900, M572, SET_PRESSURE_ADVANCE)
is preserved from the original implementation.
