Dates rendered in English even when the dashboard language was set to
French (or any other locale). The 5 shared loyalty Alpine factories
hardcoded 'en-US' in every toLocaleDateString / toLocaleString /
Intl.NumberFormat call, ignoring the user's selected language.
- Add `I18n.locale` getter to static/shared/js/i18n.js that returns
the current dashboard language code (en/fr/de/lb). Falls back to
'en' if I18n isn't initialised yet.
- Replace 'en-US' with I18n.locale in 5 loyalty shared factories:
loyalty-cards-list, loyalty-card-detail-view, loyalty-transactions-
list, loyalty-pins-list, loyalty-devices-list.
- Also fix a latent bug in loyalty-transactions-list.formatDateTime
that called toLocaleDateString with hour/minute opts (silently
ignored — same bug previously fixed in loyalty-card-detail-view).
Scoped to loyalty per session decision; other modules with the same
hardcoded 'en-US' pattern (catalog, billing, etc.) are tracked as a
follow-up.
