"""Teste TDD pentru US-007 (PRD 5.15): formular editare slim.

RED -> implementare -> GREEN.

AC-uri verificate:
  - Un singur camp VIN (fara "Confirma VIN").
  - Textarea obs (Observatii) prezent in formular.
  - Chips multi-select prestatii cu hidden inputs name="cod_prestatie".
  - Endpoint /form-chips re-randeaza sectiunea chips (add/remove).
  - Acelasi _form_editare.html in ambele modale (trimitere detaliu + editare preview).
  - Reveal dinamic odometru initial cand chips contin R-ODO/I-ODO.
