fix(P2): add metrics domain to sync_to_nova.sh — consumer export views (REQ-229)

The metrics/ export views (README.md, TRUST_SNAPSHOT.md, powerbi/) are
consumer-facing but fell outside the original 13 domains, so the first nova
release left them untracked. Adds a 14th domain 'metrics' between docs and
workflows. Updates TestSyncToNovaScript domain-order assertion to 14.
