The approve() and bulkApprove() methods in ShiftAssignmentService
hard-blocked with a 422 when all slots were filled. This was incorrect
for organiser actions — only volunteer claims (portal self-service)
should enforce capacity limits. Organiser assign() already allowed
overbooking, making the approve block inconsistent.
Changes:
- Remove capacity hard-block from approve() and bulkApprove(), replace
with audit log entry (shift.overbooked_approval)
- Add overbook confirmation dialog in ShiftDetailPanel before approving
a full shift (single + bulk approve)
- Add onError handlers to all mutations in ShiftDetailPanel (approve,
reject, cancel, bulk-approve) so errors display in the snackbar
- Add global 422 validation error display in axios interceptor via
useNotificationStore as safety net for all components
- Add PHPUnit test for approve-when-full scenario
