- Add real-time value source test: WebSocket endpoint streams get_value() at
~20Hz, frontend renders scrolling time-series chart with min/max/current stats
- Add auto-gain for audio value sources: rolling peak normalization with slow
decay, sensitivity range increased to 0.1-20.0
- Always show brightness overlay on LED preview when brightness source is set
- Refactor ValueStreamManager to shared ref-counted streams (value streams
produce scalars, not LED-count-dependent, so sharing is correct)
- Simplify acquire/release API: remove consumer_id parameter since streams
are no longer consumer-dependent

Replace single "adaptive" type with adaptive_mode sub-selector by two
distinct source types in the dropdown. Removes the adaptive_mode field
entirely — the source_type itself carries the mode. Clearer UX with
"Adaptive (Time of Day)" and "Adaptive (Scene)" as separate options.

New "adaptive" value source type that automatically adjusts brightness
based on external conditions. Two sub-modes: time-of-day (schedule-based
interpolation with midnight wrap) and scene brightness (frame luminance
analysis via numpy BT.601 subsampling with EMA smoothing).

Introduces a new Value Source entity that produces a scalar float (0.0-1.0)
for dynamic brightness modulation. Three subtypes: Static (constant),
Animated (sine/triangle/square/sawtooth waveform), and Audio-reactive
(RMS/peak/beat from mono audio source). Value sources can be optionally
attached to LED targets to control brightness each frame.
