feat(web): Temporarily disable org billing with feature flag

- Add centralized ORG_BILLING_ENABLED flag in billing-config.ts
- Add 503 guards to all org billing API routes (setup, status, subscription, credits)
- Add org event rejection to Stripe webhook with isOrgBillingEvent helper
- Add "Feature Unavailable" UI to billing pages (purchase, setup)
- Comment out billing UI in org dashboard and settings pages
- Hide auto-topup banner in credit-monitor component
- Add comprehensive tests for feature flag and webhook helper
- Personal billing (Strong subscriptions) remains fully functional

To re-enable: Set ORG_BILLING_ENABLED=true and search for BILLING_DISABLED
