## Description
This PR includes the following improvements:
* **Popular Articles Locale Selection based on Widget Locale**
* Implements priority-based locale matching:
* Exact locale match (e.g., "fr" === "fr")
* Base language match (e.g., "fr" when selected is "fr_CA")
* Variant match (e.g., "fr_BE" when selected is "fr")
* Removes default locale fallback - if no locale match is found, popular
articles section is hidden.
* Fixed **API** filter issue where the locale parameter was previously
ignored
* Hides Popular Articles section completely when no locale match is
found and Only shows relevant articles in the user's language
* **RTL Direction Handling Improvements**
* Now directly reads the `lang` attribute from HTML element `<html
lang="en">` instead of relying on `.locale-switcher` and sets direction
attribute based on language.
* Adds `data-dir-applied` attribute to prevent overlapping direction
settings between global helpers and components (eg case: Insert article
in editor dashboard)
* Update `IframeLoader.vue` to Composition API and improve the **dir**
logic
