feat: unified navigation hub + categories tab + mobile scroll fix

- Navigation: 4 items (Home, Tracker, Finance, Settings)
- Tracker page: tabs for Habits, Tasks, Stats
- Finance: added Categories tab (CRUD)
- AddTransactionModal: fixed mobile scroll with sticky button
- Home: added finance balance widget
- Legacy routes (/habits, /tasks, /stats) redirect to /tracker
