chore(eslint): add ignorePatterns + comma-dangle: never rule

Without ignorePatterns, eslint will go havoc in the locales and randomly delete strings,
probably due to some kind of vue-i18n static code analysis for keys that are not used.

Let's keep them, for now.

This doesn't stop us from manually removing the statement and running the fmt command to
see the avoided outcome.
