"""Teste US-007 (PRD 5.10): afisare operatie de service in detaliu.

Cand payload-ul contine `cod_op_service` (codul intern al service-ului), detaliul
trebuie sa afiseze „Operatie service" (cod + denumire), distinct de „Operatie RAR".
Cand lipseste (a venit direct cu `cod_prestatie`), randul nu apare deloc — conventie
"" (string gol) stabilita de US-002 in payload_view.py.

Apare atat in contextul editabil (needs_data/needs_mapping) cat si read-only (sent/error).
