fix(properties): repaint on linetype/lineweight/layer edits (#231 class)

Color/linetype/lineweight/layer are baked into the cached wire geometry
at tessellation time, so a property edit only repaints if the handler
bumps the geometry epoch. The color path did; several siblings only set
tabs.dirty (a save flag) and never re-tessellated, leaving the viewport
showing the stale look.

Route every handle-based edit through invalidate_property_targets
(mark dirty + recolor meshes + bump geometry), and full-bump the
name-based LAYER COLOR change:

- ribbon layer / linetype / lineweight dropdowns applied to a selection
- CHPROP (color/linetype/ltscale/transparency/layer)
- LAYMATCH (MatchEntityLayer)
- LAYER COLOR <name> <aci>
