Fix dormant activation to bootstrap instead of refresh

When the user clicks Load Quota from dormant state after a clean
reinstall, the cached keychain item may not exist. Using the refresh
path triggered a macOS keychain prompt because it assumed the cache
was present. Now calls bootstrapSubscription/bootstrapCodex which
properly re-reads credentials from source.
