+Migration: Create unique_items table and refactor item tracking

+This creates a proper architecture where:
+1. unique_items table stores individual item instances with their properties
+2. inventory/dropped_items reference unique_item_id instead of duplicating data
+3. When item is picked up, only the reference changes (dropped_items -> inventory)
+4. When item decays/breaks, delete from unique_items (cascades to references)
