feat(editor): editor prestatii unificat in modal - un select, un rand de chips (PRD 5.23)

Inlocuieste cele 3 controale de asociere cod RAR cu un singur rand de chips
+ un singur select care adauga instant la change. Stare = un hidden chips_state
JSON versionat; post_form_chips redus la 2 actiuni (add/remove). Optgroup
Sugestii (fuzzy/k-NN) + optiune "Nu se declara la RAR" in select, cu tinta
implicita evidentiata si placeholder care o numeste. exclus persistat prin
payload_json (treapta noua de precedenta in resolve_prestatii, round-trip complet).

Siguranta: itemii exclusi sunt scosi din payload la momentul trimiterii
(worker split_prestatii_excluse inainte de build_rar_payload + filtru defensiv),
ca sa nu ajunga NICIODATA la RAR ca codPrestatie:null.

Suita: 1680 passed, 1 skipped.
