Backend:
- User management API: GET/POST/PUT/DELETE /api/users
Supports two roles: developer, server-admin
Each user has notifyOnError toggle for email alerts
- Notification API: GET /api/notifications, mark read, unread count
- Email service: sends alerts via SMTP (mail.bshtech.net/noreply@bshtech.net)
to all users with notifyOnError=true on error/warning events
- Health monitor: checks CPU, memory, disk, Docker containers every 60s
Creates notifications + sends email on threshold breaches
Detects container down, high CPU (>90%), memory (>90%), disk (>85%)
Sends recovery notifications when issues resolve
- File-based JSON storage for users and notifications (data/ directory)
- Added nodemailer dependency
Frontend:
- Settings page: user list with role badges, email alert toggles,
add/remove user forms. Roles: Developer (blue), Server Admin (amber)
- Notifications page: real-time alert feed with type icons (error/warning/
info/recovery), read/unread state, email sent indicator, time ago display
- Added Notifications to sidebar navigation
- Wired both pages into App.tsx router
