feat(ecommerce): ADR 0007 Opcion 2 "Atelier calido" - Sub-fase 1+3

Identidad visual propia premium (ver docs-portal/docs/decisiones/0007-identidad-visual-propia.md,
revision 2). Correccion de proceso respecto al intento anterior
(v1.0.176, revertido): en vez de un token aislado en un solo boton,
esta pasada toca de punta a punta los componentes que se ven juntos en
la misma pantalla para que ninguna card quede a mitad de camino.

- globals.css: paleta ciruela/carbon-oscuro/cobre/hueso (reemplaza
  cyan/magenta/yellow/blue, confirmado sin uso previo). Domine
  (titulares/precio) + Inter (UI/cuerpo) via next/font/google -- antes
  "Inter" era solo un fallback de CSS sin garantia real de carga.
- button.tsx: variant "magenta" renombrada a "primary" (ya no es
  magenta, es ciruela solida) y su color redefinido -- renombrada en
  los 8 archivos que la usaban para no dejar un nombre enganoso.
  Radio base rounded-full -> rounded-lg, ring de foco retintado.
- product-card.tsx: badges NUEVO/TOP/descuento en la paleta nueva (no
  mas fucsia/amarillo neon), precio en Domine, radio y sombra
  consistentes con el boton.
- catalog-client.tsx: solo clases de color/radio en breadcrumb, filtro
  de precio, pills de filtro y boton de reset -- cero cambios de
  logica.

Header, footer, home y pagina de producto/drawers quedan con la
paleta anterior a proposito -- Sub-fases 2, 4 y 5 pendientes.

Validado con `docker build --target builder` (npm ci + next build con
typecheck completo) -- compila limpio.
