F3 schema-per-tenant: frontend usa tenantDb() pra tabelas tenant

- useTenantDb composable + lib/supabase/tenantClient (tenantDb/tenantSchemaName)
- tenantStore: getters activeTenantSlug/activeTenantSchema; my_tenants() RPC
  passa a devolver slug+nome (migration 07)
- codemod scripts/codemod-tenant-db.py: supabase.from('<84 tabelas + 6 views
  tenant>') -> tenantDb().from(...) em 139 arquivos (777 chamadas), remove
  .eq('tenant_id') das cadeias tenant (173)
- passada manual (4 agentes): remove tenant_id de payloads insert/upsert/update,
  selects, .or/.is de defaults; onConflict ajustado pros uniques sem tenant_id
  (singletons usam 'singleton'); realtime de tabelas tenant aponta pro schema
  do tenant ativo; repos dropam tenant_id defensivamente de payloads externos
- agendaSelects: tenant_id fora do AGENDA_EVENT_SELECT (quebraria PostgREST)
- zero embeds cross-schema (todos FK embeds sao tenant->tenant ou global->global)
- build de producao passa; 67 .js checados

Pendente (fora do escopo F3, sao cross-tenant/anon -> F4/F6):
- AgendadorPublicoPage (anon, resolve tenant por link_slug)
- Saas{Feriados,NotificationTemplates,DocumentTemplates,Whatsapp}Page
  (gerenciam defaults do sistema / views cross-tenant)
