Relatório em PDF (A4) com gerador próprio

guara report relatorio.pdf (e o botão de relatório da interface, pela extensão) gera
as mesmas seções do HTML em PDF com fontes padrão, sem dependência nova. O relatório,
em PDF e HTML, passa a trazer a situação da trilha de auditoria e o hash da última
entrada. Conferido com pdfinfo e pdftotext.
