Avoid W042 warnings like

base.FeaturedImage: (models.W042) Auto-created primary key used when not
defining a primary key type, by default 'django.db.models.AutoField'.
HINT: Configure the DEFAULT_AUTO_FIELD setting or the
BaseAppConfig.default_auto_field attribute to point to a subclass of
AutoField, e.g. 'django.db.models.BigAutoField'.

Avoid warning like

base.FormPage: (wagtailsearch.W001) Core Page fields missing in
`search_fields` HINT: Ensure that FormPage extends the Page model search
fields `search_fields = Page.search_fields + [...]`

Note: We should set that to True because that is going to become default
in a later Wagtail version. However, there were migration problems when
going from False to True so we postpone that until other problems are
fixed and we have a runnable stack.

During debugging, we sometimes get a warning, that
intranet.molgen.mpg.de is not in ALLOWED_HOSTS during edit and preview.
Is it unclear why this is required, but allow that for now and
investigate later.

Switch database field to json. This will be the only option in future
Wagtail versions anyway.

The fix is upstream now.

Remove this patch. Hopefully, "settings/local: Add intranet.molgen.mpg.de to
ALLOWED_HOSTS" fixed the same problem.

modeladmin is deprecated. Add it as an external package to ease
transition. In the longterm, the usages should be converted to
wagtail.snippets.

Wagtail's add_subpage.html now unpacks a 4-tuple including page_description,
so include model.get_page_description() in the page_types list.

Python 3.12 changed cProfile to use sys.monitoring internally, which
has a limited number of globally-shared tool slots. Concurrent requests
both trying to enable a cProfile.Profile() cause the second one to fail
with "ValueError: Another profiling tool is already active".

Wagtail 6.0 renames the classnames kwarg to classname.

See RemovedInWagtail60Warning.

Browsers request /favicon.ico unconditionally, causing a 404.

The feature used li.object.stream-field as the styling target, which no
longer exists in the Wagtail 5.x admin. The replacement (section.w-panel)
covers too wide an area and does not look good in the new design.

Keep the flag emoji labels on [de]/[en] fields.

Wagtail 5.x renders translated field headings as
span[data-panel-heading-text] rather than <label>. Use that selector to
append flag emojis after [de]/[en] markers.

wagtail.search.models.Query moved to wagtail.contrib.search_promotions.models in Wagtail 6.

WAGTAIL_USER_EDIT_FORM is deprecated in Wagtail 6 and removed in Wagtail 7.
Replace it with a UserViewSet subclass that overrides get_form_class().

get_user_edit_form was removed from wagtail.users.views.users in Wagtail 6.

Required by Wagtail's database search backend for SearchVectorField.

VideoBlock was superseded by VideoChooserBlock from the wagtailvideos
package. It is no longer referenced in live code, only in old migrations.

Replace it with a self-contained stub in each migration file so the
migrations remain importable without the original implementation.

Run

    ./manage.py makemessages -l de

Note: This commit removes many lines from django.po because in the past
the above command was run with the virtual environemnt visible in the
subdirectory "venv0" and walking over the installed Python packages.
This has been changed, the virtual environement is now hidden (".venv")
and makemessages no longer collects messages from python packages, which
is correct.

Wagtail renamed results.html to index_results.html and moved the header
rendering into the generic index view, making the local override redundant.
