feat(#127): mot de passe oublié — flux complet (API + web + e-mail)

- API publique POST /auth/forgot-password et /auth/reset-password (jeton
  password_reset_*, anti-énumération, e-mail P'titsPas)
- BDD: colonnes password_reset_token / password_reset_expires + index
- Front: écrans /forgot-password, /reset-password, lien login, mutualisation
  formulaires par token
- Template e-mail + alignement couleur; tests unitaires (auth, mail)

Merge depuis develop: branche feature/127.
