[Feature]: Add retry button on organizers directory error state

[FrankezeCode]

Problem or opportunity

When /organizers fails to load from the API, users only see an error message with no way to recover. Add a “Try again” button that re-fetches the organizers list.

Proposed solution

• Error state on /organizers includes a “Try again” button
• Clicking retry re-calls /api/organizers
• Button shows loading/disabled state while retrying
• Success after retry renders the organizer list normally
• Error message remains if retry fails
• Only src/app/organizers/page.tsx changed (unless tiny helper is needed)

HOW TO TEST

1. Run npm run dev and open /organizers with API working — list loads
2. Simulate failure (temporarily break API env or mock network error in dev)
3. Confirm error UI shows with “Try again”
4. Restore API and click retry — list loads
5. Run npm run build — passes
