Containerize InfraForge runtime for reproducible Azure deployment

[johnstel]

Problem statement

No Dockerfile/.dockerignore exists for the backend runtime. This blocks reproducible deploys and increases demo risk across environments.

Priority

P1 — identified deployment blocker for demo readiness.

Acceptance criteria

• Dockerfile added for supported Python runtime and required system deps (including ODBC support).
• .dockerignore added to keep image lean and deterministic.
• Local build/run instructions documented.
• Container startup smoke test succeeds for app health endpoint.

Checklist

• Add Dockerfile.
• Add .dockerignore.
• Verify build + run locally.
• Document image build/deploy usage in demo runbook.
