F4 schema-per-tenant: edge functions roteiam pro schema do tenant

- _shared/tenant.ts: helper (adminClient, tenantDbForId, schemaForTenant,
  listTenantSchemas, resolveTenantByChannel, tenantSchemaName)
- _shared/whatsapp-hooks.ts: hooks de tabela tenant recebem tdb; RPCs de
  credito (deduct/add_whatsapp_credits) e tenant_members seguem em supa+p_tenant_id
- inbound (twilio/evolution): tenant_id da URL -> tdb pra conversation_messages
  e notification_channels
- crons de fila (process-notification/email/sms/whatsapp-queue): varrem
  listTenantSchemas e drenam a fila de cada schema (Q3: filas sao per-tenant);
  modo single-tenant se body.tenant_id vier
- crons reminders/checks (send-session-reminders, conversation-sla-check,
  whatsapp-heartbeat-check, convert-abandoned-intakes, sync-email-templates):
  loop por tenant
- routing por tenant_id (send-whatsapp-message, send-session-reminder-manual,
  twilio-provision, de/reactivate-channel, twilio-webhook): tenantDbForId;
  channel-actions sem tenant_id varrem schemas por channel_id
- asaas-*: tenant_id do body -> tdb; asaas-webhook fica global (whatsapp_credit_purchases)
- notification-webhook (Meta): resolve tenant via channel_routing por phone_number_id,
  fan-out por message_id quando nao resolve
- caller send-session-reminder-manual passa tenant_id (evento vive no schema)

Pendente: save-intake-progress e fluxos anon por token (decisao de roteamento)
