feat: Add tickets module and PayPal integration

Introduces a new 'Tickets' module for users to submit and manage issues within their condominium. This includes defining ticket types, statuses, priorities, and categories.

Additionally, this commit integrates PayPal as a payment option for family fee payments, enabling users to pay directly via PayPal using their client ID.

Key changes:
- Added `Ticket` related types and enums.
- Implemented `TicketService` functions for CRUD operations.
- Integrated `@paypal/react-paypal-js` library.
- Added `paypalClientId` to `AppSettings` and `Condo` types.
- Updated `FamilyDetail` page to include PayPal payment option.
- Added 'Segnalazioni' navigation link to `Layout`.
