feat(lab1): Deploy OWASP Juice Shop & Set Up the Course Workflow

[Nik-ari-ai]

Goal

Deploy OWASP Juice Shop (the course's canonical attack target), produce a triage report, and bootstrap the PR-driven submission workflow you'll use for every subsequent lab.

Changes

• submissions/lab01.md — triage report (deployment, surface snapshot, security headers, top 3 risks)
• .github/PULL_REQUEST_TEMPLATE.md — PR template
• .github/workflows/lab01-smoke.yml — CI smoke test for Juice Shop

Testing

• docker run + curl returned HTTP 200 and {"version":"20.0.0"}
• CI smoke test passed green: Juice Shop up after ~4s, HTTP/1.1 200 OK
• Run: https://github.com/Nik-ari-ai/DevSecOps-Intro/actions/runs/27270463301
