Refactor group audit events to use the audit events shared template

This MR updates the Group audit events page to use the new audit events shared template. This adds the improved filtering options to this page and also adds specific filters for users so they are limited to the group only.

How the query would be called without adjustments

Query:

SELECT
    "audit_events".*
FROM
    "audit_events"
WHERE
    "audit_events"."entity_type" = 'Group'
    AND "audit_events"."entity_id" = 9970
    AND "audit_events"."entity_type" = 'User'
    AND "audit_events"."entity_id" = 1
ORDER BY
    "audit_events"."id" DESC
LIMIT 26 OFFSET 0

Plan with execution:

 Limit  (cost=0.57..25.37 rows=1 width=224) (actual time=0.003..0.003 rows=0 loops=1)
   ->  Result  (cost=0.57..25.37 rows=1 width=224) (actual time=0.001..0.001 rows=0 loops=1)
