feat: Add reports feature

Enables a new reports section in the application. This includes:
- Adding a `reports` flag to `AppFeatures` and `AppSettings`.
- Including a new "Reportistica" link in the main navigation for privileged users.
- Adding a `getCondoPayments` endpoint to the mock DB service.
- Updating the backend to support filtering payments by `condoId`.
- Providing a basic `ReportsPage` component.
