(enhancement): Include department, policy, beneficiary & insurance details in (patient-bill) API response

[ODORA0]

• Added new fields (departmentName, policyIdNumber, beneficiaryName, insuranceName) to PatientBillResource.
• Retrieved missing data from the Consommation model using BillingService.getConsommationByPatientBill().
• Implemented @PropertyGetter methods to extract relevant attributes dynamically.
• Ensured these fields are included in both DefaultRepresentation and RefRepresentation.
• Fixed recursion issue with creator by returning only the user's full name.
• Updated API response to match UI table requirements in the Billing module.

🔹 Endpoint: /ws/rest/v1/mohbilling/patientBill
🔹 Example Usage: ?startIndex=0&limit=10&orderBy=createdDate&order=desc
🔹 Ensured backward compatibility with existing patient bill retrieval.
