- we have a very crude version of this before but it just wasn't
maintainable
- one of the first things I did here was to add `include=resource` on
the API call, so it returns the fields we need without extra API
requests
- after we have the id/slug, I could build a route and model array
dynamically, or return null if we can't redirect to the object (it
doesn't exist)

- in order to show data that we might not necessarily still have around
(ie. when you delete a post, you might want the title), we're going to
start utilizing the `context` column
- right now, we store the `primary_name` for deleted events, and we also
store the `setting` `key` and `group` so we can reference it in the
audit log
- the `created_at` key is stored directly under the object we fetch as
the last event, rather than a subkey
- this meant we weren't checking the date of the last event correctly,
which broke pagination

- this adds some basic filtering and search across the audit log events
- not all of it works, but filtering by objects and searching for users
should work
