Modern Starlette requires `request` as the first positional arg to
TemplateResponse. The old `TemplateResponse(name, context)` form caused
the context dict to be passed as the template name, which Jinja2 then
tried to use as a cache key -> TypeError: unhashable type: 'dict' (500
on GET / and /roster).
