feat(action): i18n the clear-keys confirmation

Add action_i18n.sh with 22 language arms (ar, az, bn, de, el, es-ES,
fa, fr, id, it, ja, ko, pl, pt-BR, ru, th, tl, tr, uk, vi, zh-CN,
zh-TW) plus an English default. Detect device locale via
persist.sys.locale with ro.product.locale and ro.system.locale
fallbacks; split Chinese on Hans/Hant.

action.sh sources the helper at top and substitutes every echoed
literal with $(_msg <key>). The confirm() flow stays unchanged.

Wire action_i18n.sh into customize.sh's per-file extraction list so
the helper lands alongside action.sh in /data/adb/modules/tricky_store
at install time.

Pattern mirrors tricky-addon-enhanced/install_i18n.sh.
