[PROD] Django upgrade to 4.2

[szabozoltan69]

Issue

According to https://endoflife.date/django the end of support of the recent 3.2 Django LTS version is in April 2024.
So (if possible, in March) we should upgrade to Django 4.2 LTS.

(force_text -> force_str, also smart_text -> smart_str)
Requires also python 3.9 instead of 3.8.
For local database a minimum of postgres 12.
Also the snapshot tests need some refresh.

On developer side this change will require a database reload, due to we must shift to Postgresql 12.
So, from the db container: the old db can be dumped like this:

pg_dump -O    -c --if-exists -h 127.0.0.1 -U test test > /tmp/testdump.sql

Then the load to the new db can be done via a simple

\i ...testdump.sql
