Audit event details panel pagination

What does this MR do and why?

Make it easier for users to go to the next or prev audit event in the list without having to go back to the list and clicking on the next one. Adds pagination buttons to the audit event details panel to accomplish this.

This required a refactor of pushing the audit events list query up to the parent body so that it wouldn't go away when the component was removed by switching panels.

This refactor also fixed a bug where the audits list reset to page one if you clicked back when viewing an audit event details panel for an event on a later page.

As part of this, the maximization of the audit event details panel was removed as it doesn't make sense on this page and the user experience was poor. Removing the logic for it made this overall change easier.
