Event detail page has no breadcrumb/back navigation to ring or organization

The EventDetailPage has no navigation context — no breadcrumb, no "back to" link. The user lands on an event page with no way to navigate up to the ring or organization without using the browser back button. Should have a breadcrumb like:\ ← Organization Name / Ring Name or at minimum a "← Back to \[Ring Name\]" link at the top, similar to how the ring detail page has a back link. The "Hosted by" section at the bottom shows "Startup Meetup Montreal / Metro Chapter" which links to the org and ring — but that's buried at the bottom. The navigation context should be at the top.
