Subject: [PATCH] fix(qrcode): calculate margins using real size instead of DOM
 offset

Replaces the dependency on `offsetWidth` and `offsetHeight` with a deterministic calculation based on module count and cell size. This prevents incorrect (huge) margins when the QR code is generated inside a hidden container where offset dimensions are 0.

Fixes: Margin values calculation in QRCode drawing logic.
