Bug 37044: Added library branch to SCO OPAC message

Bug 37044: Added library branch to SCO OPAC message

This patch simply adds the correct branch at the end of an OPAC message on the SCO page.

To Test:
1) From the staff interface, click on a patron and add an OPAC message
   to their account.
2) Log into the SCO with this patron.
   (http://localhost:8080/cgi-bin/koha/sco/sco-main.pl)
3) Notice how in the "Messages for you" at the top, you will see the
   message, however, at the timestamp, it says something like "Written
   on 06/06/2024 by " w/o listing the library that sent it.
4) Apply patch
5) Log back into SCO module
6) Note that now in the message timestamp, it correctly lists the
   library that sent the message.
7) Sign-off
