Upstream commit bc64cd9b moved translate / LOCALES into module I18n
(with extend self). The oidc-support branch added new call sites in
login.cr / login.ecr that used the old top-level names; the merge
auto-resolved textually but left the compiler with three undefined
references.
Wrap the new call sites the same way the rest of the codebase already
does: 'I18n.translate(...)' for views and 'I18n::LOCALES' for the
constant.
