Enhance authentication and authorization components

- Refactored `AppAuth` to introduce `getGuardContextSchema` for improved user context handling.
- Updated `Authenticator` to utilize `pickKeys` for user data extraction in JWT generation.
- Enhanced `Guard` class to improve permission checks and error handling.
- Modified `SystemController` to return context schema alongside permissions in API responses.
- Added new `permissions` method in `SystemApi` for fetching permissions.
- Improved UI components with additional props and tooltip support for better user experience.
