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.
