feat: invoice due date email alerts, add favicon

- Daily cron (8:00 AM) checks created and received invoices - Alerts 3 days before due date and on due date - Summary email to INVOICE_ALERT_EMAIL with grouped tables - Tracks sent alerts in invoice_alert_log to prevent duplicates - node-cron scheduler runs inside the app process - Favicon files copied from PHP project Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
