The new counter_some / counter_limit keys (added in e8ea005) used
i18next default {{var}} braces, but lib/i18n.ts configures the
interpolator with prefix: '%{', suffix: '}' (legacy Nuxt locale-file
convention, kept verbatim when ported to RN). Result: the placeholders
rendered literally on screen ("{{count}} von {{max}} Geräten…").
Switched all three locales (DE/EN/FR) to %{var}. Also dropped the
literal "+ " prefix from the add_device label — the button now renders
an Ionicons `add-circle-outline`, so the duplicate "+" was redundant.
