ci: пайплайн с гейтами (lint, unit+coverage>=70%, security, build, image-scan, push staging-<sha>)

Refs #17, Refs #15

- lint: ruff check/format + mypy strict
- unit: pytest с --cov-fail-under=70, артефакты coverage.xml + htmlcov
- security: bandit -lll (HIGH) + pip-audit, артефакты bandit/pip-audit
- build: docker build deploy/Dockerfile -> staging-<sha> (активируется после merge #18)
- image-scan: trivy HIGH/CRITICAL --exit-code 1
- push: docker login + push в registry 192.168.1.111:3000

Обход дефекта Gitea git-http (upload-pack отдаёт пустой pack): fallback
на archive/<sha>.tar.gz, actions/checkout остаётся основным путём.

+#   lint -> unit (coverage >= 70%) -> security (bandit/pip-audit) -> build -> image-scan (trivy) -> push staging-<sha>
+# Гейты (роняют pipeline):
+#   * unit        — покрытие < 70 %  (--cov-fail-under=70)
+#   * security    — bandit HIGH, pip-audit: любая известная уязвимость
+#   * image-scan  — trivy: HIGH/CRITICAL в образе
+#   * build стартует только после зелёных lint+unit+security; push — только после зелёного image-scan.
