// KAR-782 / R36: detect the global system-dummy consultant.
//
// When a project lead is deleted and no other consultant exists, the project
// is auto-reassigned to the seeded dummy ('(System) Nicht zugewiesen',
// is_system_dummy = true) so the RESTRICT FK does not break (see
// lib/employees/reassign-lead.ts). Wherever that dummy shows up AS a project
// lead, the UI must flag it as a placeholder so it is clear the project needs
// a real reassignment.
//
// Detection prefers the is_system_dummy flag; it falls back to the seeded
// display name for projections that don't select the flag.
