📚 Description

Resolves #3321

This changes route resolution, we now check if a route exists with the localization suffix, if it doesn't it may be a route with localization disabled.

We may need to invert this conditional, check if a route exists without the localization suffix and otherwise proceed with the locale suffix, to ensure localized catchall/404 handling.
