Refactor Mikrotik model and update template structure

- Changed the parsing method in `NodeConfig` to use `parse()` instead of `parse_config()`.
- Updated the template loading path in `BaseDevice` to reflect the new directory structure.
- Enhanced the `Mikrotik` class with new methods for `system`, `interfaces`, and `vlans`, including debug print statements.
- Expanded the TTP template for Mikrotik to include structured variable definitions and groups for system, interfaces, and VLANs.
