Fix TOC Sidebar: Agregar variables CSS faltantes del template y cambiar a fuente Poppins

Problema:
- TOC sidebar usaba system fonts en lugar de Poppins
- Faltaban variables CSS del template (--color-navy-primary, --color-neutral-*)
- Variables de color estaban intercambiadas (#495057 vs #6c757d)

Solución:
1. Agregar variables faltantes a variables.css:
   - --color-navy-primary: #1e3a5f
   - --color-navy-light: #2c5282
   - --color-neutral-50: #f8f9fa
   - --color-neutral-100: #e9ecef
   - --color-neutral-600: #495057 (text default)
   - --color-neutral-700: #6c757d (text secondary)
   - --color-orange-light: #FFB800
   - --color-orange-hover: #FF6B35

2. Cambiar --font-family-base de system fonts a 'Poppins', sans-serif
   (Google Fonts Poppins ya se carga en enqueue-scripts.php)

3. Incrementar APUS_VERSION de 1.0.2 a 1.0.3 para cache busting
