refactor: Replace databaseUtil import with PlatformServiceMixin in MembersList

- Remove direct databaseUtil dependency from MembersList.vue
- Use $accountSettings() method from PlatformServiceMixin instead
- Improves code consistency and enables caching benefits
- Maintains identical functionality with enhanced error handling
