fix: correctly handle 'ku-arab' script direction in articles

Addressed an edge case where articles with the 'ku-arab' variant were displayed in left-to-right (LTR) direction despite being in Arabic script. Added logic to force right-to-left (RTL) direction for such cases, ensuring correct display.

Resolves issue with incorrect article formatting.
