## Summary by CodeRabbit
* **Refactor**
* Simplified internal pointer value construction across activity-related

- Moved PostJSONWithTimeout to platform/http
- Created platform/errors package with only types needed by ctxerr. This
way, ctxerr did not need to import fleethttp.
- Made activity bounded context use PostJSONWithTimeout directly
- Removed some activity types from legacy code that were no longer
needed

**Related issue:** Resolves#38536
This PR moves all logic to create new activities to activity bounded
context.
The old service and ActivityModule methods are not facades that route to
the new activity bounded context. The facades will be removed in a
subsequent PR.

`MarkActivitiesAsStreamed` to activity bounded context

- [x] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)

**Related issue:** Resolves#37806
This PR creates an activity bounded context and moves the following HTTP
endpoint (including the full vertical slice) there:
`/api/latest/fleet/activities`
NONE of the other activity functionality is moved! This is an
incremental approach starting with just 1 API/service endpoint.
A significant part of this PR is tests. This feature is now receiving
significantly more unit/integration test coverage than before.
Also, this PR does not remove the `ListActivities` datastore method in
the legacy code. That will be done in the follow up PR (part 2 of 2).
This refactoring effort also uncovered an activity/user authorization
