Removed remaining use of i18n from core/frontend
- i18n is an old pattern we are getting rid of in favour of tpl
- after removing i18n from helpers, there wasn't many usages of i18n left in the frontend, this removes whats left!
- this was done on a branch at the same time as Naz's commits removing i18n from the settings-related files
- hence some of these changes are minor amends to add additional messages/change names, rather than just straightup i18n->tpl
- it's a merge of both our refactors :)
