fix(ci): add .trivyignore for upstream CVEs in base images

All 16 suppressed CVEs are in upstream binaries/packages we don't control:
- Go stdlib CVEs in openbao bin/bao (Go 1.25.6) and postgres gosu (Go 1.24.6)
- OpenBao CVE false positives (Trivy reads Go pseudo-version, we run 2.5.0)
- npm bundled cross-spawn/glob/tar CVEs in node:20-alpine base image

Updated all 6 Trivy scan steps across 5 pipelines to use --ignorefile.

+# Trivy CVE Suppressions — Upstream Dependencies
+# These CVEs exist in upstream base images/binaries we don't control.
+# Reviewed: 2026-02-12 | Milestone: M11-CIPipeline
+#
+# Re-evaluate when upgrading: node base image, openbao image, or postgres/gosu image.
+
+# === Go stdlib CVEs in upstream binaries ===
+# Affects: openbao bin/bao (Go 1.25.6), postgres gosu (Go 1.24.6)
+# Fix requires upstream to rebuild with Go >= 1.25.7 / 1.24.13
+CVE-2025-68121  # CRITICAL: crypto/tls session resumption
+CVE-2025-58183  # HIGH: archive/tar unbounded allocation

+CVE-2025-61730  # HIGH: TLS 1.3 handshake vulnerability
+
+# === OpenBao false positives ===
+# Trivy reads Go module pseudo-version (v0.0.0-20260204...) from bin/bao
+# and reports CVEs fixed in openbao 2.0.3–2.4.4. We run openbao:2.5.0.

+CVE-2025-64761  # HIGH: identity group root escalation (fixed in 2.4.4)
+
+# === npm bundled packages in node:20-alpine base image ===
+# These are npm's own transitive deps at usr/local/lib/node_modules/npm/
+# Not used by our application code. Fix requires newer Node.js base image.
