Add practical_info field to producers, refactor producer form

[aurelienshz]

• Add the practical_info field to the producer model & form

  • Full-text field, using a textarea field to enable referents to add some details about how to communicate with this producer, how to get the up-to-date prices, how to order & pick up the order, how to pay... in the hope to make the referent handover process a bit smoother thanks to the relevant info being written down

• Minor refactors to producer form:

  • Fix indentation
  • Add for and id attributes to all labels & fields to enable clicking the label to select the associated fields (ids are scoped with producer_{field_name} to reduce the likelihood of an id collision with another template
  • Make the form fields 100% width

Merci pour les modifs. Ça me semble bien.

Je me demande si il faudrait faire une passe de manière générale sur les formulaires pour qu'ils se ressemblent tous en terme de taille (vis à vis des modifs que tu as faites sur la taille des inputs et l'accessibilité des labels/inputs)
