v0.6.0 – Store Layout Floorplan Editor

Added

• Store Layout & Floorplan Editor — 2D interactive canvas for designing cooperative store layouts
• Konva-based grid with zoom, pan, and zone/shelf drawing tools (select, zone, shelf, erase)
• Shelf bins with per-cell inventory item assignment and stock warning indicators
• Floorplan list with create/delete and configurable room dimensions + cell size
• Side panel for zone configuration (name, rows, cols, color) and bin-level inventory management
• Drag-to-reposition zones synced between canvas and database
• Self-healing schema migration that idempotently ensures required columns exist
• UPSERT-based zone persistence preserving inventory FK links across saves
• DevConsole overlay for global error visibility
• i18n keys (en/id) under storeLayout namespace

Fixed

• Save-zones no longer wipes shelf assignments (IDs preserved via UPSERT)
• Drag-to-reposition no longer snaps zones back to original position on next render
• ShelfPanel bins refresh immediately after item assign/unassign
• Item assignment auto-saves unsaved zones before linking inventory (FK safety)
