feat: add Phase 5 Progression & Analytics — smart suggestions, dashboard, schedule

Add auto-progression engine (ProgressionService) with rep increase, weight
increase, deload, and felt-easy acceleration rules. Add AnalyticsService for
user stats, exercise progress charts, and volume-by-day data. New dashboard
and schedule routes with Chart.js visualizations. Progression badges shown
inline on workout day view. Navigation updated with Dashboard and Schedule links.
