fix(codex-manager): surface quota-cache save failures in the menu refresh

Review follow-up: refreshQuotaCacheForMenu now guards saveQuotaCache
with the same console.warn pattern as the health check's save, so a
transient Windows EBUSY/EPERM no longer vanishes into the caller's
background .catch with zero diagnostics.
