Give the ability to change when users are considered inactive via an
environment variable `USER_INACTIVITY_THRESHOLD_IN_DAYS` or
configuration option: `userInactivityThresholdInDays`. Default remains
180 days
I've tried to use/add the audit info to all events I could see/find.
This makes this PR necessarily huge, because we do store quite a few
events.
I realise it might not be complete yet, but tests
run green, and I think we now have a pattern to follow for other events.
Adds a new Inactive Users list component to admin/users for easier cleanup of users that are counted as inactive: No sign of activity (logins or api token usage) in the last 180 days.
