/**
 * Schema Registry — central index for all admin section schemas.
 *
 * Each section's schema defines the form fields, groups, API endpoints,
 * and default values for a settings page. The AksFormRenderer component
 * consumes these schemas to render settings pages automatically.
 *
 * Schema shape per section:
 * {
 *   key: 'global.seo',
 *   title: 'SEO优化',
 *   icon: 'fas fa-search',
 *   description: '...',
 *   api: { get: () => api.getSeoSettings(), save: (data) => api.saveSeoSettings(data) },
 *   defaults: { ... },
 *   groups: [
 *     {
 *       key: 'basic',
 *       title: '基础SEO',
 *       icon: 'fas fa-globe',
 *       fields: [
 *         { key: 'site_title', label: '站点标题', type: 'input', default: '' },
 *         ...
 *       ]
 *     }
 *   ]
