feat: Implementar PWA, Analytics, Reportes PDF y mejoras OCR

FASE 1 - PWA y Frontend:
- Crear templates/base.html, dashboard.html, analytics.html, executive.html
- Crear static/css/main.css con diseño responsivo
- Agregar static/js/app.js, pwa.js, camera.js, charts.js
- Implementar manifest.json y service-worker.js para PWA
- Soporte para captura de tickets desde cámara móvil

FASE 2 - Analytics:
- Crear módulo analytics/ con predictions.py, trends.py, comparisons.py
- Implementar predicción básica con promedio móvil + tendencia lineal
- Agregar endpoints /api/analytics/trends, predictions, comparisons
- Integrar Chart.js para gráficas interactivas

FASE 3 - Reportes PDF:
- Crear módulo reports/ con pdf_generator.py
- Implementar SalesReportPDF con generar_reporte_diario y ejecutivo
- Agregar comando /reporte [diario|semanal|ejecutivo]
- Agregar endpoints /api/reports/generate y /api/reports/download

FASE 4 - Mejoras OCR:
- Crear módulo ocr/ con processor.py, preprocessor.py, patterns.py
- Implementar AmountDetector con patrones múltiples de montos
- Agregar preprocesador adaptativo con pipelines para diferentes condiciones
- Soporte para corrección de rotación (deskew) y threshold Otsu

Dependencias agregadas:
- reportlab, matplotlib (PDF)
- scipy, pandas (analytics)
- imutils, deskew, cachetools (OCR)
