Add Asterisk configuration and diagnostics support

- Updated .env.example to include Asterisk templates path.
- Modified docker-compose.yml to mount the templates directory.
- Enhanced backend Dockerfile to copy templates into the container.
- Introduced Asterisk diagnostics functionality in asterisk_profiles.py, allowing for baseline checks and diagnostics reporting.
- Integrated Asterisk diagnostics into the device diagnostics workflow in graph.py.
- Added formatting for Asterisk baseline drift reports in diagnostic_format.py.
- Updated SKILL.md to document new config baseline drift feature for Asterisk.

This commit enhances the system's capabilities for managing Asterisk configurations and diagnostics, improving overall troubleshooting processes.
