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.
Adds Dockerfile for frontend and backend, along with Nginx configuration and .dockerignore files. This enables containerized deployment and proper handling of static assets and API proxying. Updates mockDb.ts to correctly type ticket attachments.
