Backend:
- server.js: cron thumb-backfill a cada 10min com rastreio de estado
  (lastRun, nextRun, running, lastResult). GET /api/cron/status e
  POST /api/cron/run/:key para consulta e disparo manual via painel.
- routes/images.js: PUT /api/images/patients/:name — edita patient_name,
  doctor e remark em todas as imagens do paciente de uma vez.

Frontend:
- PatientsPage.jsx (/patients): tabela com colunas Nome (+ miniatura),
  Dentista, Imagens, Última atualização, Observações, Ações. Suporta
  busca, paginação infinita, editar e excluir por linha.
- SettingsPage.jsx (/settings): seção de Cron Jobs com status, resultado
  e botão "Executar agora"; seção de informações do servidor.
- EditPatientModal.jsx: edita nome, dentista e observações do paciente.
- Sidebar.jsx: add "Pacientes" (todos usuários) e "Configurações" (admin).
- App.jsx: rotas /patients (protegida) e /settings (admin).
