Course enrollment and copying stay consistent

Course enrollment now verifies that a selected pass belongs to the participant, is active, and is eligible for that exact course. When several people request the final place at the same time, Booking Bible assigns one clear outcome and keeps the waitlist within its configured limit.

Waitlist promotions use the same capacity decision, so two simultaneous actions cannot promote more participants than the course allows.

Course and workshop copies now preserve the same settings whether an owner copies one item or uses the bulk action. Course categories, instructors, passes, prerequisites, sessions, and other linked catalog choices must also belong to the current venue before they can be saved.
