feat: add payments summary endpoint and UI redesign for MyPaymentsPage

- Implemented a new API endpoint `/api/v1/my/billing/payments/summary` to provide a financial summary of payments with filters for national code, status, and date range.
- Updated the InvoiceRepository to aggregate totals for paid and unsettled invoices.
- Created a new hook `usePaymentsSummary` to fetch summary data in the frontend.
- Redesigned the MyPaymentsPage to align with the ClaimsPage structure, incorporating a design system, summary statistics, and improved filtering options.
- Added tests for the new payments summary endpoint to ensure correct functionality and filtering behavior.
