Bernard Siebens 334c706aec Reload the browser on template and static changes in dev
Adds django-browser-reload: runserver already restarts on Python changes, but
the browser had to be refreshed by hand for every template or CSS edit. It also
watches static/, so a Tailwind rebuild now refreshes the page on its own.

Mounted only under DEBUG -- it injects a script into every HTML response and
serves an open event stream, neither of which belongs in production; a test
holds that line. Its endpoint is exempt from RequireMFAMiddleware, otherwise a
not-yet-enrolled staff user has the stream redirected away and live reload dies
on the MFA enrolment page, which is exactly a page we are restyling.

"""Force MFA enrolment for privileged users.
Anyone who can change other people's data must have a second factor: Django
staff/superusers, and anyone holding an elevated ``ClubRole`` (ADMIN or EDITOR)
in *any* club. Regular members may enrol, but aren't forced to.
Enrolled users are challenged for their second factor by allauth at login; this
middleware only handles the other half — a privileged user who has never
enrolled is redirected to the MFA setup page until they do.
