A member excluded from an event's Attendance sync by an open onboarding
requirement (events.services.attendance.effective_members) previously just
never saw that event anywhere -- no row, no explanation. Two new read-side
functions mirror that exclusion instead of hiding it: club.services.
onboarding.open_requirements_blocking (per-member, "why") and events.
services.attendance.blocked_upcoming_events_for_member (which of their
upcoming events are affected).
The Calendar now shows those events as a distinct muted "Blocked" row
naming the outstanding requirement, and the event detail page shows a
"Can't sign up yet" card for the same reason -- no RSVP buttons, no lineup/
referee actions, just the explanation. Write-side blocking (who actually
gets an Attendance row, who a coach can select) is untouched.
