Refactor: Implement Fabric.js-based design canvas (FabricDesignCanvasV2)
Replaced the problematic native Canvas implementation with Fabric.js v7.4.0 for better handling of: - Text and image manipulation with selection handles - Print area visualization with magenta dashed guide box - Front/back view switching with correct product images - Color swatch selection for garment colors - Drag-and-drop positioning with proper coordinate system Key features: - Lazy-loads Fabric.js to minimize bundle size impact - Renders product mockup images as background layer - Displays print area boundaries as selectable zone guide - Text elements with font/size/color support (images pending) - Proper React hydration handling with client-only initialization Known limitations: - Image element rendering disabled temporarily (Fabric.js compatibility investigation needed) - Focus on text editing and print area alignment for MVP Files: - FabricDesignCanvasV2.tsx: Main canvas component - DesignCanvasWrapper.tsx: Client-side wrapper for SSR compatibility Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
