fix(orm): declare repositoryClass on all entities with a custom repository

On prod (opcache.preload + prod container), getRepository(Entity::class)
returned Doctrine's default repository instead of the custom one when the
entity's #[ORM\Entity] had no repositoryClass — so custom finders like
DoctorSecretaryRepository::findAllActiveBySecretary threw BadMethodCallException,
making /oauth/userinfo return 500 after login. Declare repositoryClass explicitly
on all 25 affected entities.

Also add app:create-admin command (create/promote a ROLE_ADMIN user by mobile).
