fix(i18n): sync mismatched keys between en.js and zh.js (#3534)

* fix(i18n): sync mismatched keys between en.js and zh.js (#3503)

Add 4 keys missing from en.js that are actively used in source code,
add 5 missing Chinese translations to zh.js, integrate check-i18n
into CI to prevent future drift, and skip JSON file write in CI to
avoid dirtying the working tree.
