Fix wayf_title translation key not resolving for non-openconext themes

The wayf_title key was added only to the openconext theme translations,
but the base partials (LoginBar.html.twig, header.html.twig) that use it
are shared across all themes. Add the key to the base languages/ catalogue
so it resolves regardless of the active theme.
