fix(campaigns/templates): clearer prorata phrasing — "mois restants" / "remaining months"

Iterating on the prorata disclaimer per user feedback. The previous
version ("tu rembourses le prorata non utilisé (20 $/mois)") still
read ambiguously — "non utilisé" could mean "the portion you haven't
spent" which is conceptually confusing for a one-time gift card, and
the hardcoded "$20/month" tied the template to the specific
$60/3-month campaign.

New phrasing makes the math explicit: refund only for the months
you're NOT staying.

FR:
  before — "Si tu résilies avant {{commitment_months}} mois,
            tu rembourses le prorata non utilisé (20 $/mois)."
  after  — "Si tu annules avant {{commitment_months}} mois,
            tu rembourses seulement au prorata des mois restants."

EN:
  before — "If you cancel before {{commitment_months}} months,
            you refund the unused pro-rated amount ($20/month)."
  after  — "If you cancel before {{commitment_months}} months,
            you only refund the prorated amount for the remaining months."

Wins:
  • Subject ("tu" / "you") explicit — no ambiguity on who refunds
  • Logic clarified — refund == months NOT STAYED, not "unused
    portion of money" (which doesn't quite map to a one-time gift)
  • Generic over campaign params — no hardcoded "$20/month" so the
    template works at any gift amount + commitment combination
  • "annules" (more common in QC consumer-facing) instead of
    "résilies" (slightly more formal/legal-sounding)

Applied via direct find/replace on .html + .json (FR + EN). Live
test-send queued to confirm rendering.
