Subject: [PATCH] fix(lang): pick the Kazakh and Georgian translations from the
 system locale (#16670)

With no language chosen in Settings, resolve_lang takes the language from the system locale prefix. Kazakh locales are kk_* and Georgian locales are ka_*, but their translation tables are keyed kz and ge, so both fell through to English. Map kk to kz and ka to ge for the locale-derived language. A language saved in Settings is unchanged.
