Translation Fixes

Technical Changes

Code Refactoring

• LanguageManager is now the single source of truth for all language configurations
• Consolidated language lists across OCR, translation, and settings
• Removed hardcoded language mappings in translation engine
• Simplified settings UI to dynamically populate from LanguageManager

Architecture Improvements

• UTF-8 text encoding now handled correctly throughout the application
• Plain text mode used instead of TSV for more reliable character recognition
• Translation engine simplified to only use Google Translate (free, no API key needed)
• Removed dead code for unused translation engines (LibreTranslate, Ollama, DeepL, etc.)

Known Issues

• This is a limitation of the free Google Translate API, not a bug in Ohao Lang
