fix(kpi-v2-gaps): KPI aggregator 8/12 -> 12/12 = 100%

Gaps identified par live scan apres deploiement initial v2:
- dock_coverage_pct: None (field name pct -> coverage_pct + total_pages)
- l99_score + arch_score: None (field score pas l99_score)
- business_kpi_health: None (summary nested data_completeness_pct)
- agents_active: None (endpoint .php pas .json · field health_score)

Fixes precis:
1. Dock: isset(coverage_pct) + round + sources (covered/total_pages/uncovered/by_pattern)
2. Arch: score primary fallback l99_score
3. Business: summary nested with categories/ok/warn/fail/wire_needed/completeness_pct
4. Agent: HTTP call to agent-health-global.php (V49 endpoint) + health_score field

Result (avant -> apres):
- dock_coverage_pct: null -> 100
- arch_score: 100 (stable)
- business_kpi_health: null -> 95
- agents_active: null -> 90
- l99_score: null -> 100
- Filled: 8/12 (67%) -> 12/12 (100%)
