[autodev] Update Jetson test environment and satellite-provider integration

- Added `.env.test` to `.gitignore` to exclude test environment variables.
- Enhanced `docker-compose.test.jetson.yml` to include the real satellite-provider .NET service and its PostgreSQL database, replacing the mock service.
- Updated test execution policy to mandate all tests run exclusively on Jetson hardware, deprecating the previous two-tier model.
- Revised documentation in `_docs/LESSONS.md`, `_docs/02_document/tests/environment.md`, and `_docs/04_deploy/ci_cd_pipeline.md` to reflect the new testing strategy and environment setup.
- Improved `run-tests-jetson.sh` script to ensure proper environment variable handling and satellite-provider integration.

This commit aligns the testing framework with production environments, enhancing reliability and coverage.
