Enhance ESLint configuration and update component destructuring for improved code quality

- Added a rule to allow unused variables prefixed with an underscore in ESLint configuration.
- Updated destructuring in leveling-form, logging-form, moderation-form, and welcome-form components to prefix unused variables with an underscore, improving clarity and adherence to ESLint rules.
- Expanded German and English localization files with new moderation, auto-moderation, logging, welcome, verification, leveling, economy, and fun module settings for better user experience.
