v6.1.5: Integrate Ashtottari/Yogini/Kalachakra Dasha into report pipeline

- Register 3 dasha systems in technique_registry.json
- Extend orchestrator_bridge.py with inject_dasha_results()
- Add add_timing() to ThematicReportOrchestrator
- Dashas auto-convert to TimingAnchor and inject into all 5 themes
- Verified: Yogini + Kalachakra timing anchors flow into ThemeReport
