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).

* Phase 5 Stage D — wall whole-move tool (kind-owned).
*
* 1:1 port of the legacy `MoveWallTool` (804 LoC, the most complex
* single tool in the editor). Preserves every behavior:
*
* - **Center-drag with axis lock** — wall stays perpendicular to its
* move axis unless rotated via R/T (45° steps).
* - **Linked-wall corner cascade** — neighbours sharing endpoints
* move with the dragged wall via `planWallMoveJunctions`.
* - **Bridge wall ghost previews** — when a corner separates, a
* translucent ghost shows the new wall that would be inserted.
* - **Auto-slab live preview** — `planAutoSlabsForLevel` runs every
* tick so room slabs adapt to the new wall layout in real time.
* - **Single-undo dance** — paused history during drag, restore +
* resume + reapply on commit so one Ctrl-Z rolls back the whole
* operation.
* - **`isNew` metadata strip** — first commit after a fresh wall
* placement clears the placement marker.
* - **Activation grace** (150ms) + Shift to bypass grid snap.
*
* Mounted via `def.affordanceTools.move` from `wall/definition.ts`.

/**
* Phase 5 Stage D — wall placement tool (kind-owned).
*
* 1:1 port of the legacy `WallTool`. Two-click flow: click 1 sets the
* start, click 2 creates the wall. Between clicks a vertical preview
* rectangle + length/angle measurement HUD follow the pointer. Shift
* bypasses the angle snap; Esc cancels.
*
* Not a `DragAction` — same reasoning as fence/slab/ceiling placement:
* stateful sequence of grid:click events, not a single drag-up.
*
* Mounted via `def.tool` from `wall/definition.ts`.
