feat(auth): implement authorization for PrivateKey management

- Added authorization checks in the Create and Show Livewire components to ensure only authorized users can create, update, and delete PrivateKey instances.
- Introduced a new PrivateKeyPolicy to define access control rules for viewing, creating, updating, and deleting PrivateKey models based on user roles and team associations.
- Updated AuthServiceProvider to register the new PrivateKeyPolicy, enhancing security and access control for PrivateKey functionalities.
