Feature: Filter of team log to a particular application or instance

Currently, the team Audit Log shows all events within a team, filterable by event type and user; to view events for a specific instance (there's no concept of application level events yet, see https://github.com/flowforge/flowforge/issues/1978); a user must drill down into the instance itself.

Being able to see all events associated with an instance (or application) from the Team page, would improve the UX.

Start with the Team Audit Log entry point and review issue #1978 for the planned application-level event model. Determine how instance or application identity is represented in the existing events and define the filtering behavior for the Team page; done means users can view events scoped to a selected instance or application.
