feat(salonos): implementar Fase 1.1 y 1.2 - Infraestructura y Esquema de Base de Datos

Implementación completa de la Fase 1.1 y 1.2 del proyecto SalonOS:

## Cambios en Reglas de Negocio (PRD.md, AGENTS.md, TASKS.md)
- Actualizado reset de invitaciones de mensual a semanal (Lunes 00:00 UTC)
- Jerarquía de roles actualizada: Admin > Manager > Staff > Artist > Customer
- Artistas (antes colaboradoras) ahora tienen rol 'artist'
- Staff/Manager/Admin pueden ver PII de customers
- Artist solo ve nombre y notas de customers (restricción de privacidad)

## Estructura del Proyecto (Next.js 14)
- app/boutique/: Frontend de cliente
- app/hq/: Dashboard administrativo
- app/api/: API routes
- components/: Componentes UI reutilizables (boutique, hq, shared)
- lib/: Lógica de negocio (supabase, db, utils)
- db/: Esquemas, migraciones y seeds
- integrations/: Stripe, Google Calendar, WhatsApp
- scripts/: Scripts de utilidad y automatización
- docs/: Documentación del proyecto

## Esquema de Base de Datos (Supabase PostgreSQL)
8 tablas creadas:
- locations: Ubicaciones con timezone
- resources: Recursos físicos (estaciones, habitaciones, equipos)
- staff: Personal con roles jerárquicos
- services: Catálogo de servicios
- customers: Información de clientes con tier (free/gold)
- invitations: Sistema de invitaciones semanales
- bookings: Sistema de reservas con short_id (6 caracteres)
- audit_logs: Registro de auditoría automática

14 funciones creadas:
- generate_short_id(): Generador de Short ID (6 chars, collision-safe)
- generate_invitation_code(): Generador de códigos de invitación (10 chars)
- reset_weekly_invitations_for_customer(): Reset individual de invitaciones
- reset_all_weekly_invitations(): Reset masivo de invitaciones
- validate_secondary_artist_role(): Validación de secondary_artist
- log_audit(): Trigger de auditoría automática
- get_current_user_role(): Obtener rol del usuario actual
- is_staff_or_higher(): Verificar si es admin/manager/staff
- is_artist(): Verificar si es artist
- is_customer(): Verificar si es customer
- is_admin(): Verificar si es admin
- update_updated_at(): Actualizar timestamps
- generate_booking_short_id(): Generar Short ID automáticamente
- get_week_start(): Obtener inicio de semana

17+ triggers activos:
- Auditores automáticos en tablas críticas
- Timestamps updated_at en todas las tablas
- Validación de secondary_artist (trigger en lugar de constraint)

20+ políticas RLS configuradas:
- Restricción crítica: Artist no ve email/phone de customers
- Jerarquía de roles: Admin > Manager > Staff > Artist > Customer
- Políticas granulares por tipo de operación y rol

6 tipos ENUM:
- user_role: admin, manager, staff, artist, customer
- customer_tier: free, gold
- booking_status: pending, confirmed, cancelled, completed, no_show
- invitation_status: pending, used, expired
- resource_type: station, room, equipment
- audit_action: create, update, delete, reset_invitations, payment, status_change

## Scripts de Utilidad
- check-connection.sh: Verificar conexión a Supabase
- simple-verify.sh: Verificar migraciones instaladas
- simple-seed.sh: Crear datos de prueba
- create-auth-users.js: Crear usuarios de Auth en Supabase
- verify-migration.sql: Script de verificación SQL completo
- seed-data.sql: Script de seed de datos SQL completo

## Documentación
- docs/STEP_BY_STEP_VERIFICATION.md: Guía paso a paso de verificación
- docs/STEP_BY_STEP_AUTH_CONFIG.md: Guía paso a paso de configuración Auth
- docs/POST_MIGRATION_SUCCESS.md: Guía post-migración
- docs/MIGRATION_CORRECTION.md: Detalle de correcciones aplicadas
- docs/QUICK_START_POST_MIGRATION.md: Guía rápida de referencia
- docs/SUPABASE_DASHBOARD_MIGRATION.md: Guía de ejecución en Dashboard
- docs/00_FULL_MIGRATION_FINAL_README.md: Guía de migración final
- SIMPLE_GUIDE.md: Guía simple de inicio
- FASE_1_STATUS.md: Estado de la Fase 1

## Configuración
- package.json: Dependencias y scripts de npm
- tsconfig.json: Configuración TypeScript con paths aliases
- next.config.js: Configuración Next.js
- tailwind.config.ts: Tema personalizado con colores primary, secondary, gold
- postcss.config.js: Configuración PostCSS
- .gitignore: Archivos excluidos de git
- .env.example: Template de variables de entorno

## Correcciones Aplicadas
1. Constraint de subquery en CHECK reemplazado por trigger de validación
   - PostgreSQL no permite subqueries en CHECK constraints
   - validate_secondary_artist_role() ahora es un trigger

2. Variable no declarada en loop
   - customer_record RECORD; añadido en bloque DECLARE

## Principios Implementados
- UTC-first: Todos los timestamps se almacenan en UTC
- Sistema Doble Capa: Validación Staff/Artist + Recurso físico
- Reset semanal: Invitaciones se resetean cada Lunes 00:00 UTC
- Idempotencia: Procesos de reset son idempotentes y auditados
- Privacidad: Artist solo ve nombre y notas de customers
- Auditoría: Todas las acciones críticas se registran automáticamente
- Short ID: 6 caracteres alfanuméricos como referencia humana
- UUID: Identificador primario interno

## Próximos Pasos
- Ejecutar scripts de verificación y seed
- Configurar Auth en Supabase Dashboard
- Implementar Tarea 1.3: Short ID & Invitaciones (backend)
- Implementar Tarea 1.4: CRM Base (endpoints CRUD)
