[FIX] web: `background layout` should not apply margin-top on footer

1. `background layout` report template should keep the min-height property to
avoid breaking the pdf report template.
This property is needed to display the background image at the right position
(avoid image to be crop if not a lot of invoice lines). see https://github.com/odoo/odoo/commit/41c75ad0c37d567dd43e418fda927c7ae38a3add

2. margin-top can't be applied or it will also break the pdf layout.
`min-height` will ensure that the html rendered will be high enough to looks
like the real pdf invoice anyway.
