feat(campaigns/templates): visible wrapper-expiry date in the email

Two new template variables are auto-derived from r.gift_expires_at at
render time (separately by the worker and the /view fallback to keep
them consistent):

  {{expires_at_date}}  locale-formatted FR/EN long date — "21 août 2026"
                       / "August 21, 2026". Empty when no wrapper token.
  {{expires_in_days}}  remaining days as string (rounded up). Useful
                       for tight deadlines where a date is too distant
                       to convey urgency.

Templates: a small centered badge appears between the CTA button and
the prorata disclaimer, wrapped in a Mustache section so it disappears
cleanly on campaigns that pre-date the wrapper feature.

  ⏰ Cadeau valide jusqu'au <strong>21 août 2026</strong>
  ⏰ Gift valid until <strong>August 21, 2026</strong>

Editor merge-tag panel updated so authors can drop these into custom
copy without remembering the exact variable names. The legacy
{{expiry}} field stays — it's still the right tool for promotion-end
dates that don't track the gift link's own deadline.
