Ports PR #301 (by Kevin Griffin) to the SDF text renderer. Block-nested MTEXT with inline colour codes (\C1;, \c…) collapsed to a single colour: the block cache applies ByBlock / layer-0 colour inheritance per entity, so at emit time every segment's colour was replaced with the inherited colour — including segments carrying an explicit inline override. - block_cache tessellate_sub_local: gate ByBlock / layer-0 colour inheritance on `wire_on_base_color` (a wire whose colour differs from the entity base carries an explicit override and keeps it) — #301's fix, still correct for the remaining stroke wires. - block_cache emit_wire: the per-vertex analogue for SDF text — a glyph whose colour equals the wire's base inherits the resolved colour; a glyph with an inline \C / \c override keeps it. (Previously every block glyph was recoloured with final_color, collapsing colour-split MTEXT.) - tests/text_font_rendering.rs: restore the block colour-split regression test (it had stopped compiling on main when expand_insert gained the InheritStyle param) and adapt it — and drawable_point_count — to SDF text_verts, since block MTEXT now renders as glyph quads, not colour-split stroke wires. \C (ACI) / \c (true-colour) are parsed by acadrust (mtext_format SpanProperties.color) → OCS InlineColor → the glyph's per-vertex colour.
