For #23912
new UI for activities on the global, past, and upcoming feeds. These are
the same changes in [this
PR](https://github.com/fleetdm/fleet/pull/25329), except we are
reverting the changes around fleet initiated activities as that is not
in the current activities API.
We are doing this so that the new activities can go out in a release
while the backend is still being built and will be ready later.
> NOTE: this does contain the code for cancel activity functionality but
it hidden from the user.
