Rename gesture_footer key per review feedback

Per review from bgoncal: use a new localized key so the broken
translations in Lokalise (de/nl with reversed format specifiers)
are not downloaded over the fix on the next nightly sync.

Rename kiosk.security.gesture_footer -> kiosk.security.exit_gesture_footer.
Lokalise has no translations for the new key, so all non-English
locales fall back to the English base text via --export-empty-as base.
Translators can then add properly-positional translations at their
own pace without any crash risk (both slots are %@).

The old key becomes orphaned in de/nl .strings files; the nightly
unused-strings CI check will flag it for cleanup.
