Biomekka 1.8.1

Created from Biomekka 1.7.

Dashboard layout changes:
- Main dashboard/info area now uses roughly two thirds of desktop width.
- Live camera rail sits on the right using roughly one third of desktop width.
- Top and bottom camera feeds are stacked vertically.
- Top camera is visually rotated 90 degrees anti-clockwise in CSS, without changing go2rtc/RTSP config.
- Responsive fallback stacks the layout on narrower screens.

No sensor, relay, pin, storm, telemetry, MQTT, Grafana, go2rtc config, or credential changes.
