feat: implement URL state persistence for dashboard

Adds URL search params synchronization for dashboard filters and date range
- Stores selected date range in URL for restoration on page reload
- Removes old Filter component in favor of new implementation
- Preserves filter state across page navigation

This change improves user experience by maintaining dashboard state through browser navigation and page reloads.
