+fix: Get meeting attendee emails from users table
+
+The working_group_memberships.user_email field is often NULL because it's not
+always populated when members are added. Updated the query to join with the
+users table to get the actual email, falling back to the cached value if needed.
+
+This fixes calendar invites not being sent because attendeeCount was 0.
