Add Gitea Actions CI/CD pipeline

Bring nvidia-stock-bot up to the same CI/CD maturity as adguard-cidre:
pytest suite (19 tests), multi-stage Dockerfile with a dedicated test
stage, pinned requests dependency, Gitea Actions workflow (build, smoke
test, unit tests, deprecation check, Trivy critical/high scan, version
bump + registry publish + release), and a Renovate config for automated
dependency updates.
