Add cancelled_by, cancellation_source (organiser|volunteer|system), and
cancelled_at columns to shift_assignments. Cancel flow now records who
cancelled and why. Assign flow reactivates existing cancelled/rejected
records instead of creating duplicates, preventing UNIQUE constraint
violations. Assignable-persons endpoint returns previous_assignment data
for contextual UI indicators. Frontend shows cancellation source labels,
previous assignment history in assign dialog, and "Opnieuw toewijzen"
buttons with volunteer-cancelled confirmation dialogs.

Add GET /events/{event}/shifts/{shift}/assignable-persons endpoint that
returns approved persons with availability status, conflict details, and
already-assigned flags. Improve ShiftAssignmentService conflict errors to
include section name, time slot, and time range. Replace both assign
dialogs with a new AssignPersonDialog featuring search, crowd type
filtering, availability toggle, and inline conflict warnings.
