feat: implement strangler-fig-demo Session 1 (backend + smoke script)

Builds the four-seam, three-write-path reference demo backend: case-framework (seam D stand-in), legacy-backend/frontend (SQL Server, seams A/B/C targets), and new-backend (Domain/Application/Infrastructure.*/Api implementing the source resolver, take/release-ownership, write-through translator, and owned assessment flow), wired together via docker-compose with a plain placeholder frontend standing in for the Angular portal until Session 2. All 11 Architecture.Tests pass and scripts/smoke.sh passes end-to-end against a fresh `docker compose up`, covering acceptance criteria 1-3 and 7-22. Fixes two real domain bugs found only once the stack ran for real: the BSN eleven-proof checksum trivially passes all-zero digits, and the adoption mapper silently treated a partial legacy address as absent instead of failing loudly. Also fixes several environment-specific integration issues (rootless Podman/SELinux bind-mount permissions, a buildah NuGet layer-caching bug, SqlClient's invariant-globalization incompatibility, and an nginx path-prefix mismatch for the legacy frontend).
