Fix Content-Type for Quart exceptions

mgorven · mgorven · commit effd2b2a8acc · 2025-10-28T12:43:46.000-07:00
Quart's `Response` defaults to `text/html` as the Content-Type, but when
returning exceptions the response is plain text. Set the Content-Type to
`text/plain` so that these are displayed correctly.
