feat(i18n): Integrate i18n across all components with enhancements

- Import and use vue-i18n in all components and views
- Add LanguageSwitcher component for runtime language switching
- Replace all hardcoded strings with translation keys
- Add getChatMessage to electron menu for language switching support
- Fix ConfigurationLogsView.vue conflict with upstream monaco editor changes
- Use common.* keys for shared translations (cancel, save, reset)
- Add JSDoc to all new i18n helper functions
