feat(NumberInput): updated locale format validation arabic japanese

[abpaul1993]

Closes #

This PR enhances our number parsing and validation logic to support all major Unicode numeral systems recognized by Intl.NumberFormat in validateNumberSeparators method along with the valid decimal and group seperator.
Previously, only Western digits were handled in the method.
With this update, the number input component now correctly accepts, validates, and normalizes numerals from multiple writing systems—matching real-world locale behavior across international users.

Changelog

New

1. Enhanced number parsing and validation to support all major Unicode numeral systems recognized by Intl.NumberFormat.
2. The validateNumberSeparators method now supports locale-specific decimal and grouping separators along with non-Western numerals.

Changed

• validateNumberSeparators, which was previously available for custom validation, has been updated to support Arabic and other Unicode numeral systems.
• Number input validation now normalizes and validates numerals from multiple writing systems instead of only Western digits.

Removed

• {{removed thing}}

Testing / Reviewing

• Verify that number inputs accept numerals from different Unicode numeral systems (e.g., Arabic-Indic, Devanagari).
• Confirm that locale-specific decimal and grouping separators are correctly validated.
• Ensure existing Western digit inputs continue to work as expected.
• Validate that custom validations using validateNumberSeparators behave correctly across locales.
