Otherwise, when an allowed group member is assigned to the PM it invites the user (which is unnecessary) and creates a public small post for the invite.
The previous behavior was:
1. Assign a topic to someone
2. Close the topic with the setting unassign_on_close enabled
3. Assign the topic to the same user as before
This caused small broken or empty posts to be displayed.
This commit also introduces system specs
If a topic is initially assigned to user A then reassigned to user B,
this change will make it so that notifications sent to user A are
removed. This matches the plugin's behaviour when unassigning a topic.
Only 5 assignments can exist simultaneously for a topic or its post.
The code that counted the assignments did not ignore the inactive
assignments which made the limit check more strict than it should have
been.
This change makes it possible to associate an assign notification with the `assignments` record that creates the notification. It'll be needed for the assignments tab in the new experimental user menu, see https://github.com/discourse/discourse/pull/17379.
Adds a new plugin setting that when enabled adds a status field for every assignment. This setting defaults to off.
The possible status for an assignment are customizable via yet another new setting, and the first one on this list will be the default status for new assignments.
The status is not yet show anywhere except the assign modal and the small action posts in topics at the moment. Adding status to the assignment list for users and groups will be handled in the near future.

We are already checking that assignee has access to the private message. However, admin still can be assigned as technically they have access.
We should ensure that assignee has direct access to the message.
If `SiteSetting.unassign_on_close` is enabled, an Assignment record can still exist, but be set to inactive, when a Topic is closed.
Inactivement Assignments should be ignored when comparing to the maximum number of assigned topics.
When topic is closed, we mark assignments as "inactive". Then when it is reopen and setting reassign_on_open is enabled, we bring back previous assignments.
We were already using custom fields for archive message and move to inbox. I changed custom fields solution to use active flag on Assignment model
When post is already assigned to user/group then don't allow assigning a topic to that user/group.
Similarly, right now when topic is already assigned we are not allowing to assign a post that that user.
Build a new workflow that adds a dropdown in place of the old assign button with the ability to
Re-assign a new user / group to an assigned topic
Re-assign yourself to an assigned topic
Unassign a user / group from an assigned topic
Change `topic_id` to polymorphic approach (In the next step we will allow assigning to individual post)
`topic_id` column is still used for efficient display of assigned users on topic list (to avoid scanning posts)
