Update frontend-web dependencies and implement routing structure

- Added new dependencies: @fontsource-variable/geist, @radix-ui/react-separator, @radix-ui/react-tooltip, date-fns, react-router-dom, and recharts.
- Updated index.html to set the HTML class to "dark" for dark mode support.
- Refactored App component to implement routing with React Router, replacing the previous UI structure with a layout and multiple pages (NetWorth, Debts, Invoices, Clients).
- Enhanced CSS for dark mode and added depth utilities for improved UI aesthetics.
- Expanded Redux store to include net worth, debts, and invoices slices for comprehensive state management.
