[FIX] base: use address_format in layout designer

In task-2355704 changes were made to the pdf layout designer to allow more
flexibility when setting company data. However, for the default values of both
company_details and report_footer, the data wasn't being escaped, therefore
offering security risks. Also, they didn't take into account the address_format
when computing the default value. This PR implements Markup usage in the html
fields and fixes _default_company_details to use the set address_format.
