## 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

This PR has the following fixes
1. preview of article inside the iframe, earlier this didn't work because the iframe didn't get the URL correctly. We fix that by passing the URL is a query instead
2. Emoji picker caused a weird redirect, this was only happening when the chunk was loaded async, this PR changes it to use regular loading instead
