feat: Find lang() strings and update localization keys

I will need to check the creation of files and add fakes to app/Controllers. And delete them after the tests.

If you need that, do it. Add fakes to app/Controllers. And delete them after the tests.

But it may be better to use Tests\Support namespace.
It is the namespace for testing. You do not need to delete after the tests.
See https://github.com/codeigniter4/CodeIgni...s/_support

Do I still need to add php-cs-fixer after execution? The array dump has incorrect formatting.

Yes. Run `composer cs-fix` always.
