test(catalog): add read-only live audit consistency harness

Runs the full catalog audit (runCatalogAudit) against the live hotel DB with
no repair/sql options — a pure read pass — and cross-checks the emitted
summary against independent DB + asset-dir measurements: row totals, duplicate
classname groups, orphaned catalog references and missing catalog / nitro /
icon counts must match exactly, with zero error events and a final
'batch_complete'.

Guarded by RUN_CATALOG_AUDIT_LIVE=1 so CI never runs it; loads the real .env
because vitest fakes DATABASE_URL.
