No error handling in JS code if translation is not setup correctly

[lino]

Several issues (e.g. #170 ) in this project are related to surprises in our setup process and documentation with room for improvement.

I'll look into adding error handling in the JS side to give out helpful error messages hinting to setting up the translation stuff correctly.

I installed and imported JavaScriptCatalog into my URLs and my error shows: "ReferenceError: pgettext is not defined at recurrence.js:1037:12". My django version is 4.0. I pass {{ form.media }} to my template but still doesn't work. Any suggestion? Thank you!
