chore(admin): remove useless config diff (#12545)

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - Added a GraphQL mutation to validate multiple app configuration updates, returning detailed validation results for each item.
  - Extended the API schema to support validation feedback, enabling client-side checks before applying changes.
  - Introduced a detailed, parameterized error message system for configuration validation errors.
  - Enabled validation of configuration inputs via the admin UI with clear, descriptive error messages.

- **Improvements**
  - Enhanced error reporting with specific, context-rich messages for invalid app configurations.
  - Simplified admin settings UI by removing the confirmation dialog and streamlining save actions.
  - Improved clarity and maintainability of validation logic and error handling components.
