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.

- Add printpdf 0.9.1 dependency for native PDF generation.
- New src/io/pdf_export.rs: converts paper-space WireModels to a PDF
page (per-wire stroke color, line weight in Pt, NaN-split segments).
White/near-white colors are inverted to black for print output.
- Add PlotExport / PlotExportPath messages: opens a save-file dialog
and writes a .pdf next to the drawing file.
- Add PageSetupOpen/Close/WidthEdit/HeightEdit/Commit messages: a
centered modal panel lets the user enter paper width and height (mm);
on commit the Layout object's min/max_limits are updated in-place.
- Register PRINT / PLOT / EXPORT and PAGESETUP (PS) commands in
dispatch_command; fix MVIEW error message to English.
- Layout ribbon gains a "Plot" group with Page Setup and Export PDF
ribbon buttons.

- Add active_viewport: Option<Handle> field to Scene
- Add EnterViewport(Handle) and ExitViewport messages
- Double-click on a user viewport (id > 1) enters MSPACE;
double-click on empty area while in MSPACE exits to PSPACE
- MSPACE middle-drag pans the viewport's model-space view (view_target)
- MSPACE scroll zooms the viewport's view_height / custom_scale
- Drawing commands inside MSPACE receive model-space coordinates
via paper_to_model() coordinate transform
- Active viewport rendered with yellow dashed border (vs. cyan solid)
- Camera screen_delta_to_world helper for MSPACE pan conversion
- LayoutSwitch clears active_viewport

- Layout sekme sağ-tıklamasında context menüsü (Yeniden Adlandır / Sil)
- Inline rename: sekme metin-giriş alanına dönüşür, Enter ile commit, ✕ ile iptal
- LayoutDelete: layout ve sahip olduğu tüm entity'leri kaldırır
- LayoutRename: Layout nesnesinin adını yerinde günceller
- LayoutCreate çakışma koruması: mevcut isimler arasında benzersiz ad bulur
- Escape tuşu açık rename/context menüsünü kapatır
