Phase 8: AI-driven operating and reserve fund health scores

Add daily AI health score calculation (0-100) for both operating and
reserve funds. Scores include trajectory tracking, factor analysis,
recommendations, and data readiness checks. Dashboard displays
graphical RingProgress gauges with color-coded scores, trend
indicators, and expandable detail popovers.
