BB-872: feat(editor): Add language-specific sort name generation to improve guessing

[atharvsp02]

Problem

Sort name guessing was too simplistic - only moved the last word to front, ignoring language-specific naming conventions. This caused incorrect sort names for different languages. The language dropdown existed but wasn't used for sort name generation.

Issue link: https://tickets.metabrainz.org/browse/BB-872

Solution

Implemented language-aware sort name generation that uses the selected language dropdown:

• Created guess-case-util.ts with language-specific parsing functions
• Moved language dropdown above sort name field for better UX flow
• Pass selected language ISO code to sort name generation
• Support particles for Dutch, German, French, Italian, Portuguese (e.g., "von Beethoven, Ludwig")
• Support Eastern order for Japanese, Chinese, Korean, Hungarian (no reordering)
• Support Russian patronymic names (FirstName Patronymic LastName → LastName, FirstName Patronymic)
• Extended article handling to 10 languages for collective names

Areas of Impact

Components Modified:

• guess-case-util.ts - New centralized sort name logic
• sort-name-field.tsx - Simplified, imports language-aware makeSortName
• name-section.js - Field reordering and language ISO code integration

User Experience

• "Guess" button now generates correct sort names based on selected language
• Language field positioned above Sort Name for logical workflow
• Backward compatible - defaults to English logic for other languages
