[MERGE] survey: fix certification layout

Generated PDF was shrunk down, not taking up the full width and size of the A4
format, leaving big margins on right and top. Setting `disable-smart-shrinking`
to `True` helps with this, but layout is slightly too big.  Setting `dpi` to
`96` and removing the `width` and `height` on the parent element fully fixes
the issue.

This merge also adds a boolean field `disable_shrinking` in model `report.paperformat`.
If set to True it adds one argument `--disable-smart-shrinking` in commands
that prevents the pdf shrinking. See issue[1] for more information.

This options is utilized for printing survey certificaiton.
