Add min brightness threshold to LED targets

Browse Source 
New per-target property: when effective output brightness
(max pixel value × device/source brightness) falls below
the threshold, LEDs turn off completely. Useful for cutting
dim flicker in audio-reactive and ambient setups.

Threshold slider (0–254) in target editor, badge on card,
hot-swap to running processors, persisted in storage.
