feat: Add analytics endpoints and replace MUI Grid in analytics page

Backend:
- Added 5 new analytics endpoints in DashboardController
- Implemented getUserGrowth with proper SQL CTE to avoid grouping errors
- Added getDeviceDistribution, getActivityByDay, getAgeDistribution, getEngagementPattern

Frontend:
- Removed deprecated MUI Grid import
- Replaced all Grid components with CSS Grid layout
- Connected analytics page to real backend APIs
- Added loading states and error handling
- Data now fetched based on time range selector
