security: comprehensive security audit and remediation (20 fixes)

CRITICAL fixes:
- Restrict X-View-Tenant impersonation to global admin only (was any admin)
- Add authorization to subscription endpoints (was open to any user)
- Make webhook signature verification mandatory (was skippable)
- Remove databaseName from JWT payload (resolve server-side with cache)
- Reduce body size limit from 1GB to 10MB (50MB for bulk CFDI)
- Restrict .env file permissions to 600

HIGH fixes:
- Add authorization to SAT cron endpoints (global admin only)
- Add Content-Security-Policy and Permissions-Policy headers
- Centralize isGlobalAdmin() utility with caching
- Add rate limiting on auth endpoints (express-rate-limit)
- Require authentication on logout endpoint

MEDIUM fixes:
- Replace Math.random() with crypto.randomBytes for temp passwords
- Remove console.log of temporary passwords in production
- Remove DB credentials from admin notification email
- Add escapeHtml() to email templates (prevent HTML injection)
- Add file size validation on FIEL upload (50KB max)
- Require TLS for SMTP connections
- Normalize email to lowercase before uniqueness check
- Remove hardcoded default for FIEL_ENCRYPTION_KEY

Also includes:
- Complete production deployment documentation
- API reference documentation
- Security audit report with remediation details
- Updated README with v0.5.0 changelog
- New client admin email template
- Utility scripts (create-carlos, test-emails)
- PM2 ecosystem config updates

-## Documentación
+## Arquitectura Multi-Tenant
 
-- [Documento de Diseño](docs/plans/2026-01-22-horux360-saas-design.md)
+Cada cliente tiene su propia base de datos PostgreSQL, asegurando aislamiento completo de datos:
+
+```
+horux360 (central)          ← Tenants, Users, Subscriptions, RefreshTokens
+horux_<rfc_cliente_1>       ← CFDIs, Alertas, Calendario, IVA del cliente 1
+horux_<rfc_cliente_2>       ← CFDIs, Alertas, Calendario, IVA del cliente 2
+...
+```
+
+El middleware de tenant resuelve la base de datos del cliente desde el `tenantId` del JWT, usando un caché de 5 minutos.

+## Seguridad
 
-- **4 Temas visuales:** Light, Vibrant, Corporate, Dark
-- **Multi-tenant:** Aislamiento de datos por empresa (schema por tenant)
-- **Responsive:** Funciona en desktop y móvil
-- **Tiempo real:** Dashboards actualizados al instante
-- **Carga masiva de XML:** Soporte para carga de hasta 300MB de archivos XML
-- **Selector de período:** Navegación por mes/año en todos los dashboards
-- **Clasificación automática:** Ingresos/egresos basado en RFC del tenant
+- JWT con access token (15min) y refresh token rotation (7d)
+- bcrypt con 12 salt rounds para passwords
+- Rate limiting en auth (10 login/15min, 3 register/hora)
+- FIEL encriptada con AES-256-GCM
+- CSP, HSTS, y security headers vía Nginx + Helmet
+- Admin global verificado por RFC (no solo por rol)
+- Webhooks de MercadoPago con verificación HMAC-SHA256
+- Body limits diferenciados (10MB general, 50MB bulk CFDI)
+- TLS obligatorio para SMTP
