Pagamento por checkout + consolidação por veículo (em vez de rota)

Regra de pagamento:
- Entrega.pagas agora exige status='completed' E checkout preenchido
  (antes era checkin). Afeta dashboard, painel do motorista, job 1h e
  elegibilidade das consolidações de forma consistente.

Veículo no lugar de rota na consolidação:
- migration troca consolidacoes.route_ids por vehicle_ids (jsonb + gin)
- Entrega: da_veiculo/veiculos_unicos; contar_pagas usa vehicle
- new.html.erb: filtro "Veículos" (multi-select por vehicle)
- validar.html.erb: mostra o veículo em vez do código da rota
- filtros/elegibilidade do controller passam a usar vehicle_ids
