refactor: remove unused analytics actions and integrate metrics directly

- Deleted `analytics.ts` and `deadline-analytics.ts` as they were no longer needed.
- Integrated `AnalyticsService` and `DeadlineAnalyticsService` directly into `HomePage` and `DailyPage`, streamlining data fetching.
- Updated components to utilize the new metrics structure, ensuring proper data flow and rendering.
