Update Interfaces model and Mikrotik template for improved data handling

- Made the `description` field in the `Interfaces` model optional to enhance flexibility.
- Renamed `id` to `vlan_id` in the `Vlans` model for clarity.
- Refactored the `Mikrotik` class methods to streamline raw data access and removed unnecessary print statements.
- Updated the Mikrotik TTP template to reflect changes in variable names and improve overall structure for interface and VLAN configurations.
