Allow manual language/locale override via iframe and SDK parameters

Currently, Boei determines chatbot language based on browser settings. Request to add ability to manually pass a language/locale parameter via iframe embed code or SDK initialization.


This would allow developers to force the chatbot interface language to match the page language (e.g., based on HTML lang attribute or domain), ensuring all interface elements (opening message, disclaimer, consent box, suggested questions, buttons) display in the correct language from the start.


Use case: Websites with separate domains per language (example.nl for Dutch, example.com for English) want the chatbot interface to match the domain language regardless of browser settings.
