Selecting an entity refreshed the Properties panel but the Layer / Color /
Linetype / Lineweight dropdowns kept showing the creation-time defaults
— so they couldn't be used to inspect or edit a single object's settings.
refresh_properties() now also calls sync_ribbon_from_selection(), which
walks the current selection and mirrors common values into ribbon.active_*
fields. Mixed selections leave the prior value in place (no "*Varies*"
chip yet); an empty selection restores per-tab creation defaults.
Closes#17

Commands receive click coordinates in local space (DXF coords minus
world_offset) for camera precision. Without correction, entities were
placed world_offset away from the clicked position in existing drawings
that have a non-zero centroid (e.g. UTM-coordinate drawings).
Re-add world_offset via acadrust::Transform::from_translation (f64
precision) in commit_entity before the entity is inserted into the
DXF document. Paper-space entities are exempt as they use sheet coords.
Fixes#11

- Grip points in paper space now use the 2-D linear to_px transform
(tx/ty/ortho_size) instead of the 3-D view_proj matrix, matching the
coordinate system used by PaperCanvas
- world_offset is no longer subtracted from paper-space entity grip
positions — paper-space coordinates are already unoffset (same rule
as wire tessellation in wires_for_block)
- MTEXT v_offset corrected for all attachment points: CXF glyphs sit
on the baseline and extend upward, so Top attachment needs v_offset=-h,
Bottom needs (n_lines-1)*line_h, Middle is the midpoint of the two

Entity grips() return world-space coordinates (raw DXF values). After
the world_offset change the camera view_proj is in local space, so
projecting world-space grips through it gave wrong screen positions and
hit-test failures.
- refresh_selected_grips: subtract world_offset from every grip.world
so selected_grips are stored in local (camera) space
- Grip drag: cursor/snap positions are already local space; for
GripApply::Absolute add world_offset back before passing to entity
so entity coordinates stay in world space. Translate deltas are
identical in both spaces so no conversion is needed there.

White paper fill was calculated from entity bounding boxes (paper_entity_extents),
so adding a viewport caused the paper to visually shrink to the viewport's bounds.
Now paper_limits() (layout min/max limits) is used directly, and the unused
paper_entity_extents() function is removed.

- mline.rs: MLine renders center spine + two parallel offset lines at
±scale/2 using the vertex miter directions; vertex grips; scale,
closed and style-name properties
- tolerance.rs: Tolerance renders the GDT text string via font
tessellation at insertion_point with rotation from direction vector;
insertion grip and position properties
- properties.rs: Dimension entity's style_name EditText is upgraded to
a Choice dropdown when document.dim_styles is non-empty, enabling
point-and-click DimStyle assignment without a separate panel

- properties.rs: inject 'UCS Name' Choice property for viewports when
document.ucss is non-empty; resolves current handle to display name
- update.rs: intercept PropGeomChoiceChanged for 'vp_ucs_name'; clones
UCS origin/x_axis/y_axis into viewport and sets ucs_handle — no
trait signature change required

Paper limits:
- Change A4 fallback from 12×9 to 297×210 mm in paper_limits()
Context menu:
- Translate layout context menu labels to English (Rename / Delete)
Viewport clipping:
- Replace AABB-only culling with proper Cohen-Sutherland line clipping
in viewport_content_wires(); each projected segment is now clipped at
the exact viewport boundary instead of being included or discarded whole
- Add cs_clip() and clip_polyline_to_rect() free functions in scene/mod.rs
Frozen layers per-viewport UI:
- Inject a "Frozen Layers" EditText property in the Properties panel for
viewport entities (layer names resolved from handles at display time)
- Handle "frozen_layers" in PropGeomCommit: parse comma-separated names,
resolve to layer handles, update vp.frozen_layers in-place
PDF export improvements:
- Add offset_x/offset_y params to export_pdf() for model-space normalization:
coordinates are shifted so the drawing origin maps to the page origin
- Model space export computes extents via model_space_extents() (now public)
and adds a 5 % margin; falls back to A4 landscape for empty drawings
- Skip __paper_boundary__ wire in PDF (white background covers it)
- Map yellow (active viewport border) → black and cyan (vp border) → dark
blue for print-friendly output

- Add model_space_extents() to Scene: collects key_vertices from all
model-space entities to compute an AABB.
- Add auto_fit_viewport() to Scene: sets view_target to model centroid
and derives custom_scale / view_height so the content fits the new
viewport with a 10% margin.
- Call auto_fit_viewport() in commit_entity() after a viewport is added
to a paper-space layout, so newly placed viewports immediately show
model-space content at a sensible scale.
- Scale line_weight_px by the viewport scale factor when projecting
model-space wires into paper space, so dimension arrows and annotation
lines appear at the correct visual thickness.

- Viewport ID uniqueness: commit_entity assigns max_existing_id+1
instead of always using id=2
- Lock/On boolean toggles in Properties panel (vp_locked, vp_on)
backed by status.locked / status.is_on fields
- Standard scale Choice picker: 1:500 to 10:1 (also syncs view_height)
- Numeric scale edit now syncs view_height when changed
- Standard view Choice picker: Top/Bottom/Front/Back/Left/Right/4×Iso
updates view_direction vector via apply_geom_prop
- Viewport content not rendered when status.is_on is false
- current_layout_block_handle_pub() added for external access
