✨ feat: Add language support and descriptions in product localization files

- Added language, languageDescription, and languagePlaceholder fields to product.json for multiple locales (ja-JP, ko-KR, no-NO, pl-PL, pt-BR, ro-RO, ru-RU, th-TH, tr-TR, uk-UA, vi-VN, zh-HK).
- Removed group-related fields from product.json for cleaner structure.
- Updated API calls in user services to include language parameter for subscription retrieval.
- Enhanced type definitions for subscription requests to accommodate language parameter.
