feat: status + queue updates, filters e UI

- Status renomeados e cores (Em andamento azul, Pausado amarelo)
- Transições automáticas: iniciar=Em andamento, pausar=Pausado
- Fila padrão: Chamados ao criar ticket
- Admin/Empresas: renomeia ‘Slug’ → ‘Apelido’ + mensagens
- Dashboard: últimos tickets priorizam sem responsável (mais antigos)
- Tickets: filtro por responsável + salvar filtro por usuário
- Encerrar ticket: adiciona botão ‘Cancelar’
- Strings atualizadas (PDF, relatórios, badges)
