Registered agents: populate daily class roster with flags

Registered agents lose first-instructor flags in schedules, creating first-timer processing gaps. Daily records set first-instructor flags so coordinators begin first-timer work.

Overview

Missing first-instructor flags creates first-timer processing gaps and inconsistent instructor handoffs. This workflow builds a daily class roster and sets first-instructor flags so coordinators start first-timer work reliably. The result is consistent daily operations and no manual follow-up for first-timer processing.
