refactor: restructure permission handling and enhance Guard functionality

- Introduced a new `createGuard` function to streamline the creation of Guard instances with permissions and roles.
- Updated tests in `authorize.spec.ts` to reflect changes in permission checks, ensuring they now return undefined for denied permissions.
- Added new `Permission` and `Policy` classes to improve type safety and flexibility in permission management.
- Refactored middleware and controller files to utilize the updated permission structure, including context handling for permissions.
- Created a new `SystemController.spec.ts` file to test the integration of the new permission system within the SystemController.
- Removed legacy permission handling from core security files, consolidating permission logic within the new structure.
