feat: VPORTS preset viewport configurations (2H / 2V / 4 / SINGLE)

VPORTS now accepts a layout subcommand in paper-space:
  VPORTS 2H     — two viewports side by side (horizontal split)
  VPORTS 2V     — two viewports stacked (vertical split)
  VPORTS 4      — 2×2 grid of four equal viewports
  VPORTS SINGLE — one full-page viewport

Paper dimensions are read from PlotSettings (fallback A4 landscape).
Existing user viewports are replaced and each new viewport is
auto-fitted to show model-space content.
Bare VPORTS still lists existing viewports.

Closes ROADMAP 8.5.
