fix: use plain StaticFilesStorage in dev settings

CompressedManifestStaticFilesStorage requires collectstatic to generate a
manifest before it can serve anything. Dev containers never run collectstatic
so every static asset 404s. Override to StaticFilesStorage in dev so Django
serves files directly from STATICFILES_DIRS and app static directories.
