Fix crash opening Kiosk settings in non-English locales (#4487)

The gestureFooter call site passes the taps count as an Int, but with
the format string now using %2$@ (updated in Lokalise), the SwiftGen
signature is gestureFooter(_ p1: Any, _ p2: Any). Wrap the Int with
String() so the CVarArg is a pointer type matching the %@ specifier.

Add regression tests (KioskLocalization.test.swift) that exercise all
kiosk format-string keys against every bundled locale, confirming:
- Specifier count matches English
- String(format:) completes without crash
- Each arg appears verbatim in output

Also adds a targeted test that injects each locale's gesture_footer
format into LocalizedManager and calls the real L10n function path.
