Summary

GS1 DataBar showed no resize handles on the canvas: heightLocked: true short-circuits enabledAnchors to [], disabling the transformer entirely. But only the height axis is firmware-fixed (Zebra overrides ^BR h for symbologies 1–5; Expanded Stacked uses it as per-row height) — the width axis is adjustable via ^BR magnification 1–10, which the properties panel already edits.

Changes:

• gs1databar gains a commitTransform that maps the rotation-aware width-axis scale onto magnification, clamped to the ^BR 1–10 range.
• The transformer mounts the module-width-axis anchors for a heightLocked code-1d type (middle-left/right for N/I, top/bottom-center for R/B — the bars turn a quarter).
• The 1D module-width anchor snap, live reflow and release commit resolve the module prop generically (moduleWidth on ^BY symbologies, magnification on GS1 DataBar) instead of hardcoding the name — so the drag quantises and re-renders per integer step exactly like the other 1D barcodes.
• Registry invariant: a heightLocked code-1d type must still commit the module-width axis (code-2d heightLocked types like MaxiCode keep skipping the transformer entirely, since ^BD has no size parameter at all).

Test plan

• pnpm test — new gs1databar.test.ts covers the commit contract (horizontal scaling, height ignored, 1–10 clamp, R/B axis swap); registry.test.ts pins the invariant
• tsc -b and eslint clean
• Manual: dragged a GS1 DataBar's right edge on the canvas — magnification goes 2 → 3 and the barcode re-renders wider
