fix(campaigns/templates): drop 'sans engagement' claim from Option 2

The 'sans engagement ni carte-cadeau' wording in Option 2 was confusing
for customers with an existing multi-month commitment — implies their
subscription is commitment-free, which contradicts their actual contract.

Reworded to make zero claims about the customer's commitment status,
just describes what happens if they ignore the email:

FR:
  before — 'Ne rien faire. Ton abonnement mensuel se poursuit normalement,
            sans engagement ni carte-cadeau.'
  after  — 'Ne rien faire. Aucun changement à ton abonnement actuel.'

EN (Gemini copywriter version was different from earlier templates):
  before — 'Just kick back! Your monthly subscription will continue as
            usual, with no commitment and no gift card.'
  after  — 'Do nothing. No changes to your current subscription.'

Benefits:
  • No false claim about engagement status
  • Shorter, more direct
  • Still preserves the explicit consent UX (customer knows ignoring
    is a valid choice without consequence)
  • No mention of 'no gift card' — that's implicit from not clicking
    the CTA, doesn't need to be stated
