Follow-up: Move audit events components form submission logic to main vue app

Problem to solve

The existing Admin Audit Events vue app has multiple filter and table components which all submit the form individually and make use of similar submission code.

Proposal

We should change the components to emit a submission event and then all the wrapping app to consume the event and trigger a form change. This will remove duplication, simplify the components and make it easier to move away from the form once the API is ready to be consumed.
