v1.16.2 - Health Notifications & Security Improvements

✨ New Features

Camera Health Monitoring

• Real-time Health Status Detection: Engine now monitors camera connectivity and authentication status in real-time
• Immediate Notifications: Get instant alerts when cameras go offline or have authentication issues
• Recovery Alerts: Receive notifications when cameras come back online (✅ Camera Recovered)

Polished Notification Messages

• Health status notifications now include emojis for better visibility:
  • 🚫 Camera Authentication Failed - Wrong password/credentials
  • 📡 Camera Offline - Network unreachable
  • ✅ Camera Recovered - Camera back online
• User-friendly error messages replace raw technical output

Notification Debouncing

• Alerts are sent only when camera status changes, preventing notification spam
• Single notification per status change (problem detected → problem resolved)

Per-Camera Health Notification Settings

• Configure separate notification channels for health events vs motion events
• Individual Telegram, Email, and Webhook settings for health alerts
• Global settings fallback when camera-specific settings are not configured

Test Notification Buttons

• Added "Test" buttons for all notification types in Camera Edit modal
• Standardized button styling across Email, Telegram, and Webhook tests
• Supports partial override (e.g., Camera Recipient + Global SMTP)

🐛 Bug Fixes

• Fixed AttributeError: 'StreamReader' object has no attribute 'last_health_report_status'
• Fixed duplicate <button> tags in Cameras.jsx causing syntax errors
• Improved 401/403 authentication error detection with curl fallback
• Fixed StreamReader callback not triggering for UNAUTHORIZED status

🔒 Security Improvements

• Credential Scrubbing: Sensitive RTSP credentials (username/password) are now sanitized from all notification messages
• Debug Script Removal: Removed insecure backend/debug_conn.py that could expose credentials
• URL sanitization: Double slashes in RTSP paths are now properly cleaned

🎨 UI Improvements

• Removed redundant "NO SIGNAL" and "INVALID PASSWORD" text overlays from LiveView (status badges already show this info)
• Added invalid-password.png placeholder image for authentication errors
• Consistent "Test" button styling with bordered design, hover effects, and shadows
