Fix frigate live view by capping detect FPS to 2

ONNX inference on ARM64 CPU takes ~750ms/frame, causing the detect
stream to fall behind at 5 FPS. This caps detection at 2 FPS to prevent
recording segment backlog and ffmpeg watchdog restarts. Also syncs
motion masks, zone coordinates, and alert labels from the live config.
