Improve error messaging when trying to submit to a closed form

[alyblenkin]

When a form has been closed or deleted on the server side, users get a generic "Could not find the resource you were looking for" from the server when they try to submit.

Collect should take ownership of this error message so that it can be localized. When Collect gets a 404 on submission, it should show the message:

You can no longer make submissions to this form. It may have been archived, disabled or deleted. If this is unexpected, please contact the person who asked you to fill the form.

This is similar to the related Enketo message: https://github.com/enketo/enketo/blob/0cdf70f3d61069550199cfb66ee7950c4a49972d/packages/enketo-express/locales/src/en/translation.json#L228C225-L228C305
