fix(web): reemplazar <select> nativos por shadcn Select (dark mode compat) — ADM-001

Reemplaza 13 <select>/<option> nativos en 8 archivos por el componente
shadcn Select (Radix UI). Los selects nativos ignoraban los tokens del
design system en dark mode, causando texto invisible. Se agrega mock de
pointer capture APIs en test setup para compatibilidad de Radix con jsdom.
