UID2-6806: suppress CVE-2026-32776 (libexpat) in .trivyignore

libexpat NULL pointer dereference (CVE-2026-32776) - not exploitable as our
Java services do not use libexpat. Fix requires libexpat 2.7.5, not yet
available in eclipse-temurin Alpine 3.23. Also suppressing CVE-2026-32767
which is the same CVE with a Trivy typo (transposed digits).
