The Docker/Trivy CRITICAL/HIGH gate has been failing since 08-30 on all three hawk images (CVE-2026-56408, -66046, -76641 in expat < 2.8.3-2). The failing RUN apk/apt layers are cached via cache-from: type=gha, so re-running with the same base digest restores the vulnerable layer. - Dockerfile + Dockerfile.daemon: alpine:3.23.5@fd791d74 -> alpine:3.24@28bd5fe8 (libexpat 2.8.4-r0) - internal/sandbox/sandbox.Dockerfile: node:22-bookworm-slim@d649c27d -> @4d676821 (libexpat 2.8.3-2+) Each new digest invalidates the GHA cache so the package layer rebuilds with patched expat. Verified locally: the CI trivy command exits 0 on the rebuilt amd64+arm64 hawk images and the sandbox image.

Fixes the Docker/Trivy CRITICAL/HIGH gate failing since 08-30 (CVE-2026-56408, CVE-2026-66046, CVE-2026-76641 in expat < 2.8.3-2).
Bumps both Dockerfile and Dockerfile.daemon runtime base from
alpine:3.23.5@fd791d74toalpine:3.23.5@1beb0dc0(expat 2.8.4-r0, patched). Verified locally: the actual CI trivy command exits 0 on the rebuilt image; the only remaining HIGH (CVE-2026-14456 OpenSSL) is already in .trivyignore.
