Localization on error strings

[alexwennerberg]

some error strings are localized, many are not, e.g. the embedded renderErr function in the Thread route. I assume the long term goal would be to localize these strings as well? Is there an example of the ideal pattern for localizing errors? I'd be happy to create a PR that at least sets up localization for all the unlocalized strings

thanks for raising the topic and offering to do the work but imo don't bother for the moment, i'm still of two minds re the i18n. it's currently just a lot of complexity for little actual gain right now
