Improve the design of SO/PO/INV mails together with the other changes of the
release, i.e. fixes a few imprecisions introduced by odoo/odoo#82167.
In particular, these changes enforce
* a responsive, mobile friendly layout tested on many devices and OS
* more generally, a consistent styling. Note that some redundancy in directives
is required for compatibility across email clients.
Translation files are included.
