[UDM] Update UE state machine to handle authentication retrieval errors (#3864)

Browse Source 
- In `udm_ue_state_operational()`:
  - Wrap the call to `udm_nudr_dr_handle_subscription_authentication()`
    in an `if` check.
  - On failure (`false`), log an error via
    `ogs_error("udm_nudr_dr_handle_subscription_authentication() failed")`.
  - Transition the FSM to `udm_ue_state_exception` using `OGS_FSM_TRAN()`.

This change ensures that failures during subscription authentication
REST calls are not silently ignored, and that the UE state machine moves into
an exception state for proper error handling and recovery.
