## 🐛 Bug Fixes

### Type Mismatch Error Fixed
**Problem:** Route parameters are strings, but service methods expected int
**Solution:** Changed type hints to `string|int` and cast internally

**Files Fixed:**
- `app/Services/AgentReceivablePaymentService.php`
- `app/Services/SupplierGivenPaymentService.php`

**Methods Fixed:**
- `getAgentReceivablePaymentById(string|int $id)`
- `updateAgentReceivablePayment(string|int $id, array $data)`
- `deleteAgentReceivablePayment(string|int $id)`
- `getAgentReceivablePaymentsByBooking(string|int $bookingId)`
- `getBookingPaymentSummary(string|int $bookingId, string|int|null $excludePaymentId)`

Same fixes applied to Supplier Given Payment Service.
