feat VSN-2077 : Add new endpoint to get drivers specific infos by driver Full Name

-A new REST endpoint was added to allow batch retrieval of driver information: Input: List of drivers identified by firstName and lastName Output: List of enriched driver data (driverId driverUuid , departmentName, agencyName) This avoids calling the User Service once per Geoloc record and greatly improves performance.

-Existing Admin Service APIs are reused to fetch organizational data such as department name and agency name. -The User Service acts as an aggregation layer between Geoloc and Admin services
