Status page: public monitoring at /status

- Real-time checks: web server, MariaDB, FFmpeg, disk usage
- Auto-refresh every 30 seconds
- Overall status banner (operational/degraded/outage)
- Server info: Node version, uptime, memory, PID
- Public page (no auth required)
- Responsive, theme-aware design
