Fix: Admin club management 500 error - JWT clubs claim format

- Fix clubs attribute in Keycloak to contain only UUIDs (removed role names)

- Add defensive error handling in ClubService.GetMyClubsAsync()

- Add logging for debugging club retrieval issues

- Return empty list instead of 500 error on failures

Fixes: Admin users can now manage clubs without contact admin error
