Phase 5 Stage D wall: port endpoint move, whole-move, placement (1:1 legacy)

Three remaining wall affordances ported into nodes/src/wall/ as
direct copies of the legacy implementations. Wall D is now complete.

  - move-endpoint-tool.tsx (426 LoC) — linked-wall corner cascade +
    Alt-detach + angle label. Mounted via `affordanceTools.move-endpoint`.
  - move-tool.tsx (804 LoC, the most complex tool in the editor) —
    center-drag with axis lock, linked-wall corner cascade via
    `planWallMoveJunctions`, bridge wall ghost previews, auto-slab
    live preview via `planAutoSlabsForLevel`, R/T rotation in 45°
    steps, Shift to bypass grid snap, isNew metadata strip on first
    commit. Mounted via `affordanceTools.move`.
  - tool.tsx (332 LoC) — two-click placement with length/angle HUD,
    Shift to bypass angle snap. Mounted via `def.tool`.

Editor public surface gains:
  - createWallOnCurrentLevel, snapWallDraftPoint, WallPlanPoint
  - MovingWallEndpoint type

ToolManager dispatch for `movingWallEndpoint` routes through the
registry with the legacy fallback (same shape as the fence
move-endpoint dispatch).

Wall is now A ✅ C ✅ D ✅. Stage B still pending (geometry depends on
level-batch miter data, blocked on `ctx.levelData` design decision).
Stage E pending (drop WallPanel — has slider drags + actions).
