what a new run launched now would send

`runserver 0`'s "Starting development server at <address>" doesn't work
Description
	
According to ​tutorial running 
python manage.py runserver 0:8000
is the same as 
python manage.py runserver 0.0.0.0:8000
but it's output 
$ python manage.py runserver 0:8000									 Watching for file changes with StatReloader						 
...
Starting development server at http://0:8000/ 
...
So that you can't use link "​http://0:8000/" in your browser. Output should be "Starting development server at ​http://0.0.0.0:8000/" when providing "0:8000" in command line in order to stay consistent with docs.

Work only inside this repository checkout. Make the code change the task
describes, keeping the diff focused — no drive-by refactors.

When you are done, leave your changes committed or in the working tree;
they are collected automatically.

Stay on this snapshot checkout (`task/ycb_django_pr16145`). Never checkout, pull, or rebase onto `main`. That branch is a README-only orphan.
Stay on this HEAD. Do not fetch another default branch. Push only on the Cursor-created `crazy-cursor/…` side branch from this HEAD.

Some past runs of this task were launched with a different prompt (the prompt template changed since, or those runs predate this benchmark's stored prompt). Each run persists the exact prompt it sent at launch — that per-launch record is the audit trail; this page shows only the current one.
