Subject: [PATCH] Corrige polling excessivo em /voto-individual/
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Adiciona @login_required em votante_view para que usuários
  anônimos sejam redirecionados ao login em vez de receberem o
  template com auto-reload.
- Corrige bug do relógio: setInterval recursivo dentro de
  startTime() acumulava timers exponencialmente. Trocado por
  setTimeout, mantendo apenas um timer pendente.
- Move o script de reload/relógio para dentro do bloco
  {% if not error_message %} para que a variante de erro não
  agende reloads de 30s.

Reduz drasticamente o volume de requisições que disparavam o
rate limiter (RATE_LIMITER_RATE=35/m) quando vários parlamentares
mantinham a tela aberta atrás do mesmo IP NAT.
