# Fix Plan: Missing _config_roles_callback method

## Problem
The `TicketSetupView` class has a button that references `_config_roles_callback`, but this method doesn't exist. This causes an `AttributeError` when the `/ticketconfig` command is used.

## Solution
1. Add `_config_roles_callback` method to `TicketSetupView` class
2. Create `ConfigRolesSetupView` class to handle config roles selection

## Files to modify
- `commandes/ticket/__init__.py`

## Changes
1. Add `_config_roles_callback` method in `TicketSetupView` (after `_categories_callback`)
2. Add `ConfigRolesSetupView` class (after `StaffRolesSetupView`)

## Status
- [x] Add `_config_roles_callback` method
- [x] Add `ConfigRolesSetupView` class
