Enhance BaseDevice validation and update Mikrotik model

- Introduced a new method `_validate_template_groups` in `BaseDevice` to ensure TTP templates declare all required and optional sections.
- Updated `_REQUIRED_SECTIONS` and added `_OPTIONAL_SECTIONS` to improve template validation.
- Modified the `vlans` method in `Mikrotik` to streamline raw data handling and added debug print statements for clarity.
- Revised the Mikrotik TTP template to include structured variable definitions and improved group handling for interfaces and VLANs.
