Improve Arabic Handwriting Enhancement and Numeral Support

Please add a handwriting enhancement feature that allows users to select a specific handwritten word, line, or section and improve its appearance automatically.

The feature should clean up and refine the handwriting while preserving the user's original handwriting style, so the result still looks naturally handwritten rather than being converted into a typed font.

Arabic handwriting support should be a major priority. Arabic handwriting has different letter connections, shapes, and writing characteristics, so the enhancement should be specifically optimized to handle Arabic handwriting accurately and naturally.

The feature should also properly support both numeral formats commonly used within Arabic text:

- Western Arabic numerals: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

- Eastern Arabic-Indic numerals: ٠، ١، ٢، ٣، ٤، ٥، ٦، ٧، ٨، ٩

Users may use either format when writing Arabic, so the app should recognize, preserve, and enhance both formats correctly without changing or misinterpreting them.

This numeral support should be considered part of Arabic handwriting recognition and enhancement as well.

Ideally, the enhancement should be applied directly after selecting the handwriting, without requiring complicated steps or converting the handwriting into typed text.
