FR: Add support for RTL languages and specific fonts in agent deployment settings

[mimalef70]

I recently had the opportunity to introduce chaindesk to several people at the Gitex exhibition in Dubai. However, a recurring feedback was that the users of these companies primarily speak Arabic, and they require support for "Right to Left" (RTL) languages in various components of chaindesk, including widgets, iframes, and standalone applications.

To address this issue, I suggest that we add a checkbox option for RTL languages in the agent deployment settings. Additionally, it would be beneficial to support fonts that are commonly used for Arabic text, such as Vazir and Naskh, to improve readability for users who prefer these fonts.

By implementing these changes, we can ensure that chaindesk is more accessible and user-friendly for Arabic-speaking users, ultimately enhancing their experience and satisfaction with our platform.
