RevenueCat isn't set up, so exporting revenueCatWebhook forced a Secret Manager entry:
defineSecret('REVENUECAT_SIGNING_KEY') runs at module load, and Firebase validates every
declared secret across the whole codebase at deploy time (even functions excluded via --only),
failing with "no latest version of the secret". Comment out the export so the file isn't loaded
during discovery — no secret, no validation. revenueCatWebhook.ts (already migrated to v2) is
untouched; re-enable by uncommenting the export, seeding the real key, and deploying it.
