add get endpoint node status

[louisevelayo]

Context: The current version of the Node monitor only sends a status report at a predefined interval set by the node provider. However, for an improved user experience, it would be beneficial to allow the node provider to request the status of their nodes at any time.

Problem: The current version of the Node monitor lacks the capability for node providers to request real-time status updates outside the predefined reporting interval, which can be limiting during auditing or debugging phases.

Solution: To provide more flexibility, a new GET endpoint will be implemented, enabling node providers to request the status of their nodes on-demand. This enhancement depends on issue #26.
