UI: estilar enlaces del índice de admin y del panel de servicios de la cuenta

Se veían como enlaces azules sin estilo. Ahora:
- /admin: rejilla de tarjetas (icono + etiqueta + flecha) con hover dorado.
- /account (servicios): chips con borde, fondo de panel y hover dorado en vez de
  enlaces subrayados azules.
