Add barqinspect Command for Payment Inspection

[tareknaser]

Currently, we have a barqrouteinfo command that simulates a payment and returns the potential route that barq could take if barqpay is executed.

We propose adding a new command, barqinspect. This command will allow users to inspect a specific payment from the history using its ID. It should provide details about whether the payment completed successfully or failed, along with the associated logs.

This feature is dependent on implementing a storage solution (#7).
