feat(manager): auto-provision WhatsApp Bridge on demo create/destroy

- Add POS_INTERNAL_URL config for cross-VM API calls
- create_demo now calls POS /internal/whatsapp-bridge after tenant creation
- delete_tenant now destroys bridge container before dropping DB
- Graceful fallback if bridge provisioning fails
