[IMP] report: widen company address space on reports

Change the external_layout_header, with the use of
span tag and display inline-block property instead
of div tag, because without using it, the address
under-line occupied the whole col-xs-6 block, for
small address also. By using display inline-block
the length of address underline will same as length
of address. And col-xs-6 will increase the address
space for log address lines.
