Enhance ModelView class with iterable and indexing support

- Added iterator, length, and item access methods to the `ModelView` class, allowing it to handle single models and lists more effectively.
- Refactored the `vlans` method in the `Keenetic` model to restore functionality for decoding VLAN descriptions, improving data processing consistency.
