Fix | Refactor class-config to ensure compatibility with translations on WP6.7

[g-dom3]

This PR updates the Complianz plugin to comply with WordPress 6.7’s stricter requirements for translation loading, addressing a "Doing It Wrong" error caused by premature loading of translated strings. The load_plugin_textdomain() function was moved to a dedicated method called at the appropriate lifecycle stage, ensuring proper functionality, and its premature invocation in the hooks() method was removed.

A new load_translated() method centralizes the loading of translation dependencies and executes on the init hook with priority 0 for early initialization.
Modularization was improved with methods for handling common translations, dynamically adding Brazil-specific options, and loading configuration files based on user preferences and regions. Action priorities were adjusted for consistency, ensuring proper sequencing of load_translated(), init(), and load_pages().
