Add RTL (Right-to-Left) language support

[abd3lraouf]

Description

The app currently lacks support for RTL (Right-to-Left) languages, which makes it difficult for users who speak Arabic, Persian, Urdu, and other RTL languages to use the app comfortably.

Why is this important?

• RTL languages are used by hundreds of millions of speakers worldwide
• Proper RTL support ensures the UI mirrors correctly (text alignment, icons, navigation elements, etc.)
• Makes the app more accessible and inclusive to a global audience

Suggested implementation

1. Add RTL layout support in the AndroidManifest:
   android:supportsRtl="true"

2. Use start/end instead of left/right for layout attributes

3. Ensure Compose UI components use Alignment.Start/Alignment.End instead of absolute alignments

4. Test with RTL languages enabled in Android settings

5. Ensure message bubbles and chat UI elements mirror correctly

6. Consider text direction detection for mixed LTR/RTL messages
