Phase 5 Stage D: revert curve + whole-item move affordances to legacy

User-reported regressions made it clear that my D-ports of the curve
and whole-item move tools introduced more friction than they removed.
The legacy CurveFenceTool / CurveWallTool / MoveFenceTool /
MoveSlabTool / MoveCeilingTool ship more polish than the new ports do
right now:

  - Legacy curve tools pre-snap the pointer position to the 0.5m grid
    BEFORE projecting onto the chord normal, and they Shift-toggle to
    a free-place mode. The ports skipped both — finer math, but the
    user-visible UX regressed (laggy because the cascade resolver fires
    per move, history feels broken near the no-op threshold).
  - Legacy whole-item moves use scene.update per tick which keeps
    hosted children visually aligned. The live-drag mesh.position port
    cleared the offset before the GeometrySystem could rebuild,
    producing a one-frame teleport on commit.

Drop the affordance registrations for those tools — the ToolManager /
MoveTool dispatch falls back to the legacy per-kind tools when the
registry doesn't declare the affordance. Stage D progress preserved
for: fence move-endpoint (linked cascade + alt-detach), slab/ceiling
boundary + hole editors, fence placement, slab placement, ceiling
placement.

The kind-owned files (curve-tool.tsx, move-tool.tsx, actions/curve.ts,
actions/move.ts) stay on disk for the next iteration — when they
reach parity with legacy UX, re-add the affordance entries.
