feat: add workspace agent connect and app open audit types (#16493)

This commit adds new audit resource types for workspace agents and
workspace apps, as well as connect/disconnect and open/close actions.

The idea is that we will log new audit events for connecting to the
agent via SSH/editor.

Likewise, we will log openings of `coder_app`s.

This change also introduces support for filtering by `request_id`.
