jedarden 66e640522d feat(signal): add ambient confidence score and link health monitoring
Implements per-link health metrics that gate and weight detection algorithms:

Per-Link Health Metrics (LinkHealthScorer in ambient.go):
- SNR Estimate (40% weight): motion/quiet deltaRMS ratio via log10 mapping
- Phase Stability (30% weight): phase variance with 0.5 rad threshold
- Packet Rate Health (20% weight): actual vs configured rate
- Baseline Drift (10% weight): hourly normalized L2 change

Gating Effects:
- BreathingDetector: disabled when health_score < 0.7
- FusionEngine: link contributions weighted by health_score

Dashboard Visualization:
- 3D link line color: green (1.0) → yellow (0.5) → red (0.0)
- 3D link line thickness: 2px (>0.7), 1px (0.4-0.7), 0.5px (<0.4)
- System-wide Detection Quality gauge in header
- Link Health panel with per-metric breakdown and sparklines

API: GET /api/links returns health_score and health_details for each link

Tests:
- Health score computation with weighted sub-metrics
- SNR mapping: SNR=100 → 1.0, SNR=10 → 0.5
- Phase stability: variance=0 → 1.0, variance=0.5 → 0.0
- Breathing health gating at 0.7 threshold
- Fusion engine link weight verification
