"""Formulaire public d'inscription + champs bénévole associés

Revision ID: 0013_signup_form
Revises: 0012_badge_template_size
Create Date: 2026-09-21

Deux tables : `form_template` (configuration par édition — ouvert/fermé) et
`form_field` (champs activés, présence = activation). Sur `volunteer` :
`photo`/`photo_content_type` (formulaire public), `companion_wish_note`
(vœu de compagnon en texte libre, résolu ensuite par la coordination),
`self_declared_available`/`willing_to_pay_fee` (cases à cocher purement
informatives). Voir `app/api/forms.py`.
