owning-a-home 404s caused by urls.py

[csebianlander]

There are three 404s in our latest analytics report that are caused by redirects set up within cfgov/cfgov/urls.py, rather than redirects.conf or the Wagtail admin panel:

• /owning-a-home/resources/adjustable_rate_loan_estimate.pdf redirects to /static/owning-a-home/resources/adjustable_rate_loan_estimate.pdf
• /owning-a-home/resources/mortgage_closing_forms.pdf redirects to /static/owning-a-home/resources/mortgage_closing_forms.pdf
• /owning-a-home/resources/checklist_mortgage_closing.pdf redirects to /static/owning-a-home/resources/checklist_mortgage_closing.pdf

There are redirects set up in Wagtail for all six of these 404s, which should lead to these URL paths respectively:

• https://files.consumerfinance.gov/f/documents/cfpb_buying-a-house_adjustable-rate-loan-estimate.pdf
• https://files.consumerfinance.gov/f/documents/cfpb_buying-a-house_closing-forms_guide.pdf
• https://files.consumerfinance.gov/f/documents/cfpb_buying-a-house_mortgage-closing_checklist.pdf

The problem is that the redirects set up in Wagtail are being overriden by the wildcard operation in urls.py:

    re_path(
        r"^owning-a-home/resources/(?P<path>.*)$",
        RedirectView.as_view(
            url="/static/owning-a-home/resources/%(path)s", permanent=True
        ),
    ),

I do not know enough about the static assets that still exist within owning-a-home to know whether and to what degree this operation (which was set up back in 2016) is still necessary, but at a minimum I think we need to somehow make an exception for PDF files, which all should live on the files server at this point.
