Connect event feed to backend

The event feed page should query the event findAll endpoint of the backend with a pageSize of 10 (take: 10, skip: 0 initially)

Optionally also implement pagination, so show how many pages are available based on the event count and page size, and do another query with updated take and skip values when the user turns the page. (useMutation is probably needed for this)

depends on #35 and #49

Start by checking dependencies #35 and #49, then locate the event feed page and the backend event findAll endpoint. Implement the initial query with take: 10 and skip: 0; if pagination is included, show available pages from the event count and update take and skip when the page changes.
