fix: docker should not wait for user input

After running collectstatic once locally, if you try to docker compose up, it will ask whether to overwrite existing static files, and then error out because, I presume, it was waiting too long.

0.900   File "/usr/local/lib/python3.12/site-packages/django/core/management/__init__.py", line 442, in execute_from_command_line
0.900 You have requested to collect static files at the destination
0.900 location as specified in your settings:
0.900 
0.900     /app/staticfiles
0.900 
0.900 This will overwrite existing files!
0.900 Are you sure you want to do this?

0.909     if input("".join(message)) != "yes":
0.909        ^^^^^^^^^^^^^^^^^^^^^^^

------
failed to solve: process "/bin/sh -c python manage.py collectstatic" did not complete successfully: exit code: 1

So I added the --no-input flag. Not sure if it's even needed in prod/test since it should be all in docker. But if we run into other timeouts because it randomly decides to ask for user input then it might be useful...
