Biomekka 1.8.7

- Changed top camera CSS sizing so the rotated portrait feed is roughly full card width.
- Top camera frame now uses aspect ratio 8:9, making it exactly twice the height of the 16:9 bottom camera frame at the same card width.
- Rotation remains CSS-only; no go2rtc, RTSP, Nginx, sensor, relay, telemetry, MQTT, or pin changes.
- Reduced timelapse player max height to 280px to stop it eating the page.
