-- Migration: Refactor roles table to use code as primary key
-- This migration drops and recreates the role-related tables with the new schema

-- Drop existing tables (CASCADE removes dependent foreign keys)

DROP TABLE IF EXISTS "user_roles" CASCADE;--> statement-breakpoint
DROP TABLE IF EXISTS "roles" CASCADE;--> statement-breakpoint

-- Recreate roles table with code as primary key

	"active" boolean DEFAULT true NOT NULL,
	"created_at" timestamp DEFAULT now() NOT NULL,
