Answer 1

Your entity class Groupe is incorrect.
It will not extend Sonata admin class.
Methods configureListFields, configureFormFields, configureDatagridFilters should not be here. They must be in separate admin class(an analog symfony controller class)
Example:
<?php
namespace Tic\ClasseBundle\Controller\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;
class GroupeAdmin extends Admin
{
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('id')
->addIdentifier('name')
->add('country');
}
protected function configureFormFields(FormMapper $form)
{
$form
->add('id', null, [
'attr' => [
'readonly' => true,
],
])
->add('name')
->add('country');
}
protected function configureDatagridFilters(DatagridMapper $filter)
{
$filter
->add('id')
->add('name')
->add('country');
}
}

Answer 2

The entity and admin page should be separated from each other. Your entity shouldn't extend the Admin class Sonata provides, but you should create a new file instead which extend the Admin class.
sonata.admin.post:
class: Tic\ClasseBundle\Admin\AdminGroupe /*Locating the admin file*/
tags:
- { name: sonata.admin, manager_type: orm, group: "Gestion de classe", label: "Groupe" }
arguments:
- ~
- Tic\ClasseBundle\Entity\Groupe
- ~
calls:
- [ setTranslationDomain, [AcmeDemoBundle]]
I highly suggest to read the documentation (again) Sonata provides see: https://sonata-project.org/bundles/admin/3-x/doc/getting_started/creating_an_admin.html
