agatha 12176471e1 Feat: Add production-grade multi-stage container image for API
Two-stage build (uv builder + python:3.12-slim runtime) with non-root
user (UID 1001), no dev deps, layer-cache-optimised dep install, and
graceful SIGTERM shutdown. Verified by api/tests/build/verify_production_image.sh
covering build, health endpoint, non-root, stdout logging, secret-free
layers, missing-env-var exit, and dep-layer cache hit. All 102 integration
tests still pass; shellcheck clean.
