[FIX] purchase_request: render HTML notification body correctly

The purchase order confirmation notification posted on the purchase
request rendered its <h3>/<ul>/<li> tags as literal text in Odoo 19.

The body was built as a plain str while html_escape() (which returns a
Markup) was passed as an argument to self.env._(). In Odoo 19 the
translation function escapes the whole translated string when any of its
arguments is a Markup (odoo/tools/translate.py), so the surrounding HTML
markup ended up escaped too.

Build the message with Markup().format() from the start, keeping the
translatable strings free of HTML and applying html_escape() outside of
self.env._(), mirroring the sibling _purchase_request_confirm_done_message_content
method. The same broken pattern in purchase_request_allocation is fixed
as well.
