Fix: viewport MSPACE activation and navigation

Browse source 
Four bugs prevented viewports from working like AutoCAD model-space windows:

1. Dead-code double-click block: `!is_down2` was always false because
   `is_down2 = sel.left_down` is captured while the button is still held
   (before the selection block clears it). Changed to `is_down` so the
   double-click handler actually fires.

2. Inverted pan direction: pan_active_viewport used `-=` on the delta
   returned by screen_delta_to_world, which is the same delta that cam.pan
   *adds* to its target — causing reversed drag. Changed to `+=`.

3. Zoom not cursor-centered: zoom_active_viewport now accepts an optional
   paper-space cursor position and adjusts view_target so the model point
   under the cursor stays fixed (same as cam.zoom_about_point).

4. ESC did not exit MSPACE: CommandEscape now calls ExitViewport when
   active_viewport is set and no command is running.

Also added MS/MSPACE and PSPACE command aliases, and MspaceCommand /
PspaceCommand messages so MS auto-enters the first viewport.
