feat(services): add rent service functions

This commit introduces new functions to handle rental services in the src/services/rent.service.ts. Functions created handle rental CRUD operations such as createRentService, updateRentService, deleteRentService, also additional utility functions such as getUserRentService and getRentByIdService that deal with user-associated rentals were introduced. These new functions serve to simplify rental management and improve our services for rental handling.
