Hakan Seven 9a1211842d perf: cache paper-canvas tessellation and viewport projections (Option L) 
Add two epoch-keyed caches to eliminate per-frame work in paper-space layouts:

paper_sheet_cache — caches wires_for_block(layout_block) as Arc<Vec<WireModel>>.
Previously paper_sheet_wires() re-tessellated all paper-space entities (title
block, annotations, viewport borders) on every mouse-move frame.  Now it is an
O(1) Arc clone.  entity_wires_arc() reuses the same cache so a geometry-change
frame triggers only one tessellation pass even when both the GPU renderer and
the Iced canvas are active.

paper_projected_cache — caches projected+clipped wires per viewport handle.
viewport_content_wires() now uses model_wires_for_viewport_arc() for the
tessellation step (already O(1) via viewport_wire_cache) and stores the
projection+clip result keyed by (vp_handle, epoch).  Navigation frames
(pan/zoom on the paper sheet) are O(N_viewports) Arc/slice copies instead of
O(N_entities × N_points × N_viewports) tessellate+project work.
