## Summary by CodeRabbit

- **Chores**
  - Removed an outdated configuration flag from the default settings.

- **New Features**
- Enhanced multi-organization support for admin settings, with certain
configurations (e.g., email verification) now conditionally hidden.
- Updated the presentation of notification and warning messages,
switching from link-based displays to more prominent callout styles for
improved clarity.
