This commit transitions all styles in app.css in the Django pipeline
to being compiled by webpack in an app-styles bundle, and renames the
various files to now be processed as SCSS.
To implement this transition, we move the old CSS file refernces in
settings.py and replace them with a bundle declared in
`webpack.assets.json` and includedn in the index.html template
Tweaked by tabbott to keep the list of files in `app.css` in
`webpack.assets.json`, and to preserve the ordering from the old
`settings.py`.
We haven't seen significant traffic from the legacy desktop app in
over a year, and users using it get a warning to upgrade since last
summer, so it's probably OK to stop providing special fonts for it.
We use the attrs property provided by render_bundle function of
django-webpack-loader to add `nonce="<csp_nonce_val_here>" to
js scripts being rendered by webpack.
This should make it easier to find the templates that are actually
part of the core webapp, instead of having them all mixed together
with the portico pages.
