agenda Fase D: adapter Clinica usa agendaBilling.service

AgendaClinicaPage espelha Fase C: useAgendaStatusChange composable
+ AgendaStatusChangeConfirmDialog plugado.

onUpdateSeriesEvent reescrito:
- Materializa virtual se preciso (via createClinic com status='agendado'
  + tenantId)
- updateClinic({ status }) no DB
- applyStatusChange(eventoId, row, novoStatus) ramifica via dialog
  quando preciso
- loadClinicRange() refetch apos applied

Mesma feature parity de Melissa pra status change na Clinica:
multa, taxa cancelamento tardio, consumir saldo, gerar cobranca
pacote saldo, reverse transition trava — tudo via agendaBilling.service.

Fase C (Rail) + Fase D (Clinica) fechadas. Os 3 layouts (Melissa/
Rail/Clinica) agora compartilham o billing core do agendaBilling.
service via composable useAgendaStatusChange.

Pendente (residual incremental):
- Indicadores visuais (3 canais) nos 3 layouts
- Antecipar/Revogar pagamento no popover de Rail (Rail nao tem
  popover separado — usa AgendaEventDialog direto; precisa
  refactor maior)
- Doc de ajuda
