Refactor/event details page

[peterhudec]

Description of change

This PR refactors the /events/{id}/details and /events/{id}/attendees paths to React. It also fixes:

• Missing trailing segments in breadcrumbs
• The title in the header is now always the {event-name} (previously it was "Events" when on the /events/{id}/details} page

Test instructions

1. Go to /events
2. Click on one of the events
3. You should land on /events/{id}/details
4. Click on the Attendees item on the left hand side navigation
5. You should see
   • The Attendees side bar navigation item highlighted as selected
   • Path in the address bar to have changed to /events/{id}/attendees, without page reloading
   • A list of attendees to the right of the sidebar
   • The breadcrumbs should be Home > Events > {event-title} > Attendees
6. Click on the Details nav item
7. You should see
   • The Details side bar navigation item highlighted as selected
   • Path in the address bar to have changed to /events/{id}/details, without page reloading
