Add audit logs to Vuex store

[jrohrbaugh0812]

As a developer, I want to add a list to the state to store all audit logs so that every time a user goes to the audit log page, a trip to the backend isn't needed to fetch the audit logs. Lastly, I want to add a fetch action to fetch audit logs based on the search filters.

Tasks:

• Add a property to the state called auditLogs, which should be set to an empty list.
• Add actions for fetching all audit logs from the backend. This action should take in an object containing the search filters, and passing that object into the body of the request.
