refactor(highway_3d): h3d-carve cut-16 — move initScene + bg-helpers + buildBoard to src/scene-init.js

VERBATIM-MOVE: initScene() (4215-5704), bg-helper functions (5706-6221), and
buildBoard() (6242-6571) extracted from screen.js into a new ES module
src/scene-init.js as createSceneInit({...~200 DI params}) → { initScene,
buildBoard, _bgUnmountStyle, _bcSyncMode }.

All factory-scope variables that other modules read go through getter+setter
pairs (no plain-value shorthands) to avoid the fork-class bug from cut-15.
Local alias pattern applied throughout: const _x = new T.Thing(); setX(_x);
closures use getX() to read current value.

Test retargets: highway_3d_context_loss, fret_spacing, pool_warm,
render_order, score_fx, sustain_bloom, sustain_rail, wide_fov — all updated
to search src/scene-init.js alongside screen.js, and patterns broadened for
DI forms (getRen().domElement, getFretG(), getFretTubeGeo(), etc.).

414/414 tests pass. ESLint: scene-init.js 0 errors, 1 max-lines warning.
