[FIX] #384 p.4 — allineamento label/campi modale Policy (override floating-label BI) + cache-buster style.css 20260618

La modale 'Modifica Policy' (e ogni modale con form legacy .form-label) mostrava
l'etichetta sovrapposta al valore: BI definisce .form-group label{position:absolute}
(spec. 0,1,1) che vinceva sulla .form-label legacy. Aggiunto override
.form-group .form-label{position:static} (spec. 0,2,0). Bumpato ?v= di style.css
su 38 pagine. version.json -> 1.23.2.
